It isn't actually the job of law enforcement to earn certain amounts of revenue, it is their job to enforce the law that the legislature has enacted.
Agreed, but that is not where their priorities lie.
Also if they were going to seize the assets of open bazaar then they could simply seize the keys from two of the four devs (assuming they are using a 2 of 4 multi sig address) to sign/push a TX out of their address
Ok, I see where the confusion is. We are both talking about the developers using multisig for their measly 18 BTC to fund development and the future dealers using multisig BTC as part of the open bazaar protocol in order to protect their assets from either the feds stealing it or the developers stealing it.
Are you suggesting you believe the feds will go after developers for creating a non-profit agnostic marketplace? If so why haven't they gone after developers who create torrent software and protocols in a non-profit and voluntary method yet?
