The real reason why, is making anon donation from anywhere, via in cash, which means so e level of physical exchange.

Canada went banana, because crypto was used for the protests. Had it been cash, it would be harder to donate from 1000s of miles away.

I think this is all about foreign influence, or at least, the scared perception of it being easier.

Imagine, your enemies funding the scariest parts of your soceity, an all anonymously, and from the comfort of 100% remote.

This is the fear, I think.
