It's far simpler. All you need is KYC to generate anon tokens, and then make it illegal to store any linking information and illegal to use any such information in court.*

The issue is no one in government would buy into this. You'd prevent them from catching bozo criminals who can't use a VPN.

*For example, you get up to N anon tokens a day you can use for anoning online. Only a count is stored daily to limit generations.
