People talk about crypto like offshore bank accounts and cash never existed.

How does the revolutionary leader of a Sub-Saharan country who suspects the deposed leader has funds in an offshore bank account in a jurisdiction that doesn't even recognize the incoming regime get the money? Violence.

In hyper-legalistic societies like the U.S., yes, the police may sometimes have trouble finding proof that survives court scrutiny. (Though I'd guess most people aren't practicing good opsec around their crypto.) But that isn't most of the world. I don't see the Indian police having any trouble arresting and searching someone on reasonable suspicion of operating a hidden wallet.
