how would that be different from what paypal already offers?
Because Paypal is a corporation, centralised and auditable by a national government plus they deal in FIAT currencies primarily (they happen to have started allowing Bitcoin but that is tangential).
If a country demands their records for the prosecution of a criminal case, they must give them. There is nobody to sanction with most cryptos.
The early use of Bitcoin was 95% Russian and other oligarchs using it for money laundering. That and dictators etc. It was funding terrorism and illegal trade very very directly.
That it (the blood) is diluted now.. hardly matters to me.
