If there is a push to "outlaw individually held crypto wallets [...] forcing holders to turn over personal wallets to government regulated exchanges", then I imagine it would intensify
So would enforcement and it's all pretty trackable. There's no way to spend it without leaving a trail and no way to convert it to fiat either. Gold you could just melt and reform or hand over. Tracing a public blockchain would be infinitely easier since the info is in fact right there in the open. It'll get a bit dicey with international wallets, but that'll be addressed as well.
Bottom line, crypto is not like cash or gold. It's publicly trackable.
