These are really great words .May be some poor guys who could not afford to pay such huge transaction fee of $3 would be worried about.

OP's question seems very logical from a newbie's point of view.He just thinks that the BTC price has increased high and it still remains high only for the reason that people are not able to withdraw their bitcoins for selling.Otherwise,due to high sell order,BTC price might have fallen down.

But beyond that,there is still a huge buy wall for bitcoins due to entry of CME,CBOE,etc.,
