Same reason you can't make a knight move with a bishop - it's against the rules of chess. You can't castle when you are in check and you can't castle if the king moves through check. Also, something I learnt quite recently is that if you are in a tournament and playing strictly by the rules you must touch your king first when castling. If you first touch the rook then you must move the rook by any legal move but castling is no longer allowed.
Originally posted by MahoutI believe this varies by federation; I don't have my USCF rulebook handy, but I believe it had a special note mentioning that you could touch either piece first. Now I have to look this one up after work before I TD another event. 🙂

USCF: may touch either piece first
Originally posted by WulebgrThe USCF used to use the FIDE rule as well, but they changed it recently. I can only speculate that they did it because of the scholastic push and the desire to make the game as kid-friendly as possible.

Personally I find that it is hard to play a tournament around here once you're out of (high) school as non-scholastic events are few and far between.
Originally posted by zebano"The U.S. rule regarding castling is also far more sensible, according to [Steve] Immit. FIDE Laws describes the process of castling such that the king must be moved prior to the rook. Immit describes this as a rule that, 'serves no other purpose than to make disputes.' The USCF allows either piece to be touched first."
