What the hell does this mean? It sounds like you're saying the prices are wrong because you can't take the money out, but I just cashed out 390 MTGUSD for $390 in my paypal 15 minutes later. Anyone with a bank account can withdraw directly from mtgox in a few days (normal banking timeframes) if they meet the $800 minimum. If you are referring to the $1000 a day limit, there may be a point here. However, I couldn't care less about that since I would be really lucky to need more than a week to withdraw my funds. I'm a small player, and I like to imagine there are more like me than people with multiple thousands invested. Cash inflows are good, but IMHO, the more distributed the coins are the healthier the economy will be.
Plus, we are working on lifting this limitation. This will however require filling some requirements (KYC-like, we cannot send huge amounts of funds blindly to just anyone, that's what the law says). More details to come~
