There's no reason not to allow them. You might legitimately prohibit them if unsleeved, but in sleeves there's no difference. Tournaments that aren't run by WotC do allow proxies, though I think Star City Games limits you to 5 proxies, which isn't enough to solve any budget problems. Again, obviously, there's no reason as far as gameplay goes. SCG does traffic in used cards.
The guys who run tourneys are also often guys that participate in the secondary market heavily. Having an 'open to any proxy' tournament would screw their bottom line. The whole point of them running tourneys is to keep excitement in the game and sell more cards on the secondary market.
