Define possession of a wallet or account as money laundering, and arrest 100 people.
The laws already permit this by regulation, I presume the reason they haven't done this already is because major players in the government have assets at risk - but if the Treasury Secretary and AG wake up one day and decide to ban it, it will be over in six hours as all BTC, etc falls to zero and stays put.

Biden’s ChiComm buddies already did that. Bitcoin still going strong, even in China. I suppose the weenie deep state could shut down the internet. Now, that would kill Bitcoin, and the 21st century. Then we could all run around in loincloths, chasing quails with spears.
