With well-implemented and sufficiently widespread P2P there’d be too many people to sue.

(I can’t name a strong contender in the wild currently, but I would also hope that this regulation, if successfully implemented, catalyzes some progress in this direction as a side effect.)

You just sue the early adopters and write some articles about how the new system is used for criminal activity only and then completely ban it. You can't have technological solutions to political problems.
