attack the incentives...
have dedicated govt agencies going after the crypto money trail, and disrupt the theives. this happened in the pipeline hack.
otherwise, the thieves will continue thieving with nothing to stop them.
thats why we have the police and other such agencies in the real world.
when thieves go after the commons (libraries/hospitals) - we the public taxpayers have every incentive to demand action of our govt as there is nobody else who can help here.
why are the british taxpayers not demanding action ?
