so more of our money flows to the parasites.
If you're referring to bitcoiners
wanting to trade bitcoins for USD and vice versa, then yes.
If there was no need to exchange bitcoins for USD, we wouldn't have a problem.
I suppose the need/want ratio will change over time but for now I imagine most people think it is a "need" and their perception makes the reality. I'm not American so it is even more irksome to be affected by this kind of thing.
On the "parasite" front, it strikes me that the FinCen website becomes an invitation to all the other jurisdictions listed in the registration to send Gox a C&D threat/invitation for $5000 (California-style). If so that would be at least a quick quarter-million dollars into various government coffers. (Are these things renewable annually?). Gox can treat it as a cost of doing business with Americans, but the fees will come out of somebody's pocket eventually, perhaps customers globally.
So far the parasites are not killing the host, but it's early days.
Mischief questions: if an American in McMurdo Station, Antarctica does business with Gox, does that put Gox in violation of FinCen's guidelines? How about CIA operatives around the world who might want to use
BTC "on business" - should Gox just decline to deal with them in case it might annoy FinCen?
