Cash requires no such thing. Neither do easily available gift cards. There is a little more friction involved.

As a merchant I have zero desire to sell online to an anonymous buyer because the fraud risk is too high. I have to know whom I’m shipping to and how they’re paying for it.

We were talking about digital payments right? Cash isn't digital.

What about people wanting to buy abortion pills?

Cash, at a pharmacy.

Crypto doesn’t make that any better.

Neither does online ordering. Online orders have to have a degree of KYC.

It's illegal to sell abortion pills. What now?

Cash seems to have functioned pretty well for the illegal drug trade for a long time.

What’s your point? Crypto somehow facilitates illegal financial transactions? That is not going to make normal people eager to use it.

At least not until normal things become crimes.
