Dark Jezter said:Actually, I just took a closer look at both the rapier and the elven thinblade, and I noticed something...
Rapiers are not light weapons ...
From the SRD:
Weapon Size: Every weapon has a size category. This designation indicates the size of the creature for which the weapon was designed.
A weapon’s size category isn’t the same as its size as an object. Instead, a weapon’s size category is keyed to the size of the intended wielder. In general, a light weapon is an object two size categories smaller than the wielder, a one-handed weapon is an object one size category smaller than the wielder, and a two-handed weapon is an object of the same size category as the wielder.

A rapier's weapon size is the same as the intended weilder - Medium in the case of a typical medium sized elf - which is why the rapier is not a light weapon but a short sword (small) or dagger (tiny) is.
