It is not like you cannot get USD out of MtGox, you have to wait. The waiting part is what prevents people from going there.
No. You really can't get it out, if you read in the forums the queue is getting longer and longer and Gox can only process 10 per day. If that. You really think a US bank is going to process a wire from Mt.Gox after their funds were seized by DHS?
Gox doesn't need a US bank, though. There are countless high-margin offshore payment processors who can cut foreign checks and push through wires via intermediary banks. US banks won't touch Gox, but plenty of payment processors will. Gox thus far is clearly unwilling to shave its profits (and it may have to shave them quite considerably) to do what is necessary to meet withdrawal volume.
The question is -- how much market share will Gox bleed before it does anything about it? If they are simply holding out for a US-facing bank that will continue the old status quo, good luck to them. That ain't happening.
No matter what, Gox needs to bleed out a lot of market share before they can be a sustainable business.
