The book might suggest that spikes are the weapon, but that's patently impossible.
Spikes wouldn't be floating in the air causing someone to be hit.
I don't know what you think you're trying to prove by that statement. The spikes are on the shield, the spikes do the piercing damage, the shield doesn't.
What you're saying is like claiming that a sword isn't a weapon, because someone has to swing it - so thier /hand/ is actually the weapon.
Therefore, if you spend +2 enchantment to make a Bashing Shield which is the weakest enchantment in the entire game, I don't see how adding spikes to a 1d8 weapon wouldn't cause more damage.
Bashing is an enchantment clearly meant for regular (non spikey) shields. Shield and armor spikes are enchanted /sepparately/, as weapons.
It'd be perfectly reasonable to rule that it doesn't even fucntion when placed on a spiked shield - after all, it's /Bashing/, not 'Impaling.'
I think it'd be more fair and reasonable to allow a bashing spiked shield to either bash or be used to do piercing damage with the spikes. That's also probably the best 'legal' result you could get.
I'd be willing to push it slightly and allow /Bashing/ to increase the damage of the spiked shield to d8 and be both piercing and bashing - effectively, it's a morningstar that can be used as a light weapon. Actually, that's probably too generous.
Explain how it would do the same damage. (Reasonably - don't hide behind rules interpretations)
Well, let's look at a standard weapon in the PH as an example:
A Morningstar and a heavy mace both do d8 damage. The only difference is that the Morningstar is spiked. Since it's spiked it does bashing + piercing damage - not d10 damage.
Reasonably, it'd do less damage - the d6 damage from the spikes, since the magic aplies to the shield. If you want to argue that the spiked shield is, itself, a complete, unified weapon, then the bashing enchantement couldn't be aplied to it - it's not an weapon enchantment.
