It looks like bisq is basically a clone for localbitcoins. To do a trade, you still have to send USD back and forth via paypal, ACH, etc. It seems like you'd run into the same money changer law violations that have been used to nail LBC users in the past.

I do however agree with you that cryptocurrency is a genie that the government doesn't quite understand yet. I think that cryptocurrencies are going to do for finance what the internet did for the way people communicate with each other. The entire financial system is going to be replaced.
