One would hope that a thoughtful court of law would recognize that the usefulness to the public of greatly reduced time to complete a transaction ( a few seconds at most), along with  transaction fees that are a tiny fraction of main chain fees, would overwhelmingly dwarf the negative impact of the few illegal transactions that may be occurring (much like with cash).

This is why I am kind of unimpressed with Phoenix wallet running away from the US market so quickly after the Samourai charges, when they weren't charged with anything.
