So can one person explain to me why these banks that are supposed to be throwing roadblocks in front of MtGox "because they want to stop/slow down bitcoin" do not throw these roadblocks in front of Bitstamp or BTC-E or any other big exchange? Why is Bitstamp able to process my deposit in 2 days? And how is it possible that a withdraw from Bitstamp also only takes 2 or max 3 days?
It's possible they are just doing it to MtGox at the moment because that is the biggest exchange. If Bitstamp became the biggest exchange then perhaps something would happen to them, then.
It's also possible that entities who are especially cooperative and/or are in a position which makes it possible to squeeze them at some point in the future are left unmolested. This to mold the future Bitcoin landscape into a form which will be more easy to manage at a later time.
I'm not saying that this is what is happening, and to be honest I rather doubt that any particular group with significant organizational ability is focused that clearly on the addressing the potential future threat of the Bitcoin ecosystem at this point. But it is a viable hypothesis to test.
Again as I mentioned recently, I put forward this hypothesis about Mt. Gox when they seemed to have had a free ride (even though they were the largest by a mile.) The ride came to a crashing halt at about the time the Coinlabs deal came crashing down it seemed to me. It also needs note, however, that Mt. Gox operates in a funny jurisdiction. (I find a lot of stuff about Japan to be funny...and tragic...)
