A monk's unarmed strikes are considered natural weapons for the purpose of spells or effects that enhance or improve natural weapons. INA both grants and is an effect that improves natural weapons, therefore a monk's unarmed strikes are considered natural weapons for this purpose, thus fulfilling the "natural weapon" prerequisite for the feat and allowing monk's, with a +4 BAB as well, to take the feat. All that seems quite clear to me. How does "granting" the effect vs. "being" the effect change how it applies to monks?
If "granting" an effect made a difference then monks could not benefit from, say, a potion of Magic Fang. The potion is not a spell it is (per the SRD) "a magic liquid that produces its effect when imbibed" and so must go the 'effect' route to benefit a monk. Clearly the potion "grants" an effect (that effect being a +1 to natural weapons) rather than "being" the effect, but I doubt anyone would dispute that a monk benefits from drinking it.
What am I missing in your "grants" vs. "is" argument?
When you cast
magic fang two conditions have to satisfied for the creature to get the benefit. One, it has to be a living creature, and two, it has to have a natural weapon. These two conditions are different. A creature has to be alive to be a valid target, but you can cast the spell on a living creature that lacks a natural weapon. A druid might cast it on herself, and then wildshape into a bear, for instance; at the moment the spell is cast it has no effect, but the effect kicks in when a natural weapon is acquired by wildshaping. You can't cast it on an zombie (even one that has natural weapons) because undead aren't alive. Even if you used a
wish to restore the wolf to life, the
magic fang spell would still be wasted; you have to bring the wolf back to life first, then cast
magic fang.
In other words, the
magic fang checks its target once to see if it is an eligible recipient of the spell; then it checks continuously to see if it is an eligible recipient of the spell effect. It checks to see if the target is alive, and then it checks for natural weapons. If the first check is failed, the spell fails. If the second check fails, the spell hangs around and waits to see if the subject of the spell acquires some natural weapons.
Look at the INA feat. There are also two conditions it checks. First it checks to see if the creature has a natural weapon; if the creature doesn't have a natural weapon, it can't take the feat. This is a continuous check; just like a creature could have a strength penalty that prevents them from benefiting from
power attack, so too could a creature stop benefiting from INA if it stopped having a natural weapon. The second check is to see if the creature has a natural weapon; if it does, they are enhanced.
See the possibility for confusion? The two conditions for
magic fang are satisfied in different ways. The first condition of
magic fang is satisfied by the target being alive, the second by the target having natural weapons. In the case of INA, the first condition is the same as the second condition, and it is very tempting to think of them as one condition. But they are resolved separately.
The RAW, it is argued, says that there is an exception for monks that allow them to be treated as having natural weapons, but only when the second condition is checked. The RAW, it is argued, are silent about the first condition, and so the monk's unarmed attack is treated normally, as a manufactured weapon. The fact that the second condition is satisfied means nothing; a zombie wolf has a natural weapon, and so satisfies the second condition of
magic fang but it does not satisfy the first condition of
magic fang, and so the spell doesn't work.
Similarly a monk satisfies the second condition of INA; when the feat looks to enhance a natural weapon, it is satisfied by the monk's unarmed attack. But it is argued that the first condition is not satisfied by the monk's unarmed attack. Why? Because the special rule about monks' unarmed attacks counting as natural weapons applies only to spells and effects that enhance those attacks. And meeting the first condition doesn't enhance the natural attacks, only the second one does. Remember the druid that casts
magic fang on herself; being a living creature makes her an eligible target, but doesn't provide any benefit. Satisfying the first condition doesn't provide any benefit, only the second one does. So only the second condition treats the monk as having a natural weapon, not the first.
Hypersmurf's example of an associate membership card to an exclusive club is a good one. If you are a full member (or accompanied by a full member) you can enter the club, and you can use your card to get cheap drinks. But the card doesn't get you in the door.
The question about human monks and INA is whether they can "get in the door." We agree that they could "get cheap drinks" once they were in, but we are saying that their card won't gain them admission. The card satisfies the bartender that they should be treated as members, but it doesn't satisfy the bouncer. And if the bouncer is not satisifed, they won't even see the bartender.
With INA the "associate membership card" is the rule that a monk's unarmed attack is treated as a natural weapon for the purpose of spells and effects that enhance natural weapons. Those beneficial effects are the cheap drinks, and the benefit part of the feat is the bartender. But the card doesn't satisfy the bouncer (the prerequisite part of the feat), and so they don't get the effects; they don't even see the bartender.
For
magic fang the bouncer checks to see if the target is a living creature; the bouncer is the target line of the spell. The effect line of the spell checks to see if the target has natural weapons; that's the bartender, and the drinks are the bonus that
magic fang provides. But you don't get to see the bartender or get any drinks unless you pass the bouncer.
For INA, the argument goes, a human monk can't get past the bouncer, so no drinks.
This is the argument if the INA feat grants effects, rather than *is* an effect.
If INA *is* an effect, then the argument is much simpler. INA enhances a monk's unarmed attacks, and so it treats monks as having natural weapons. It is like having a trial membership in the club. Even though you haven't paid your dues, you are treated as a full member; the bouncer lets you in, and the bartender gives you cheap drinks. Monks are treated as having natural weapons for the purposes of INA, and so a human monk can take the feat as soon as the BAB prerequisite is satisfied.
The argument is then whether the rule about a monk's unarmed attacks etc. is like an associate membership card (that doesn't get you past the bouncer) or like a trial membership card (which does). The rule will be like an associate membership card if INA grants effects, and it will be like a trial membership if INA is an effect.
So that's how "grants" and "is" are different, and why the difference is important.
