Its starting to sound like you dont understand how to purchase bitcoins. You cant just buy bitcoins without going through at least 2 types of exchanges. Minimum being Bank wire > MTGox
While that may be your experience, I've literally never bought bitcoins on an exchange of any kind. I actually predate MtGox, but only by a little, and as of yet have not been forced to use a bank transfer of any kind to aquire bitcoins, so I know for a fact that it is possible to buy bitcoins entirely outside of the current financial structure if you are both patient & determined.
