uh... hmmm.. I don't care. And I don't care. I think. And even if Case 2 applies, in both cases, I still don't care.
Prohibition:
Case 1: I don't live in the United States -> I don't care
Case 2: If it affects me anyways: I'm likely continuing using Bitcoin over a VPN server which is domiciled in a more Bitcoin friendly country (see "Surveillance")
Surveillance (if prohibition case 2 applies):
Case 1: If the feds are too incompetent to catch me -> I don't care
Case 2: If the feds are sophisticated enough to catch&sue me -> I'm stopping using Bitcoin. In this case, it's mandatory to collect proof from my fully encrypted computer
