> Even those are solvable problems,

Are they?

Historically, there have been a lot of people eager to erect barriers to make payments difficult for those who want to gamble, sell porn, buy porn, donate to controversial political causes, avoid taxes, sell drugs, buy drugs, etc etc

So a system that lets me send $40/month of untraceable cash to strangers on the internet might face a lot of opposition.

You can send $40 month of untraceable cash to strangers via the post office, how is that any different?

You can send $40 a month easily but receiving $40 a month from 20000 people is difficult and will raise questions.
