It makes none of these statements. You are interpreting based on what makes sense to you.
All it says is that you are immobile. "Immobile" means you cannot move. "Move," in D&D, means exiting one 5' square and entering another one.
I see no indication anywhere in the item description that states you cannot take standard actions, such as attacking, casting a spell, etc...
Please quote the relivent section of the item description if you disagree.
I will quote the relevant section of Pinned instead:
"Held immobile (but not helpless) in a grapple."
What does held immobile mean here? Does it only mean that you cannot move as per movement?
NO
Why? Because you cannot do that when you are merely grappled. While grappled, you cannot just walk away. You have to break the grapple before you can move away. If your definition were correct, then you would be "held immobile" when grappling, but that is not the case.
Hence, "held immobile" while pinned means MORE than no movement while grappled.
It means that you cannot do anything except try to escape or cast a (mostly) mental spell when pinned. No attacks. No movement. Nothing else.
"You can attempt to cast a spell while grappling or even while pinned (see below), provided its casting time is no more than 1 standard action, it has no somatic component, and you have in hand any material components or focuses you might need. Any spell that requires precise and careful action is impossible to cast while grappling or being pinned. If the spell is one that you can cast while grappling, you must make a Concentration check (DC 20 + spell level) or lose the spell. You don’t have to make a successful grapple check to cast the spell."
"If You’re Pinned by an Opponent
When an opponent has pinned you, you are held immobile (but not helpless) for 1 round. While you’re pinned, you take a –4 penalty to your AC against opponents other than the one pinning you. At your opponent’s option, you may also be unable to speak. On your turn, you can try to escape the pin by making an opposed grapple check in place of an attack. You can make an Escape Artist check in place of your grapple check if you want, but this requires a standard action. If you win, you escape the pin, but you’re still grappling."
Pinned also does not have an entry on the Favorable and Unfavorable Attack Conditions Attack Roll Modifiers table because you cannot attack when pinned. You can attack while grappled, but the loss of mobility from being pinned denies you the ability to attack while pinned.
If you cannot attack or cast (most) spells or move when held immobile when pinned, the same applies to the Iron Bands which also state that they bind you, hence, you are bound and immobile AND helpless.
The other aspect of this is that the bands allow you to break out as per bound (strength check or escape artist), not as per pinned (escape artist or grappling check). The reason is that you are going against an object, not a creature. Grappling and Pinned are illogical because those are conditions created by creatures, not objects. Entangled or Helpless are the only logical object versus creature conditions here, and this definitely does not meet the criteria for Entangled.
The question for you here is: Is a creature helpless if he is tied up with ropes? If so, why? If not, why?
