I miss the days of sending someone a letter with some cash for them to associate address A with line B. All I'd have to do to stay essentially anonymous is finding a someone with bad record keeping.

Suddenly someone shows up with address A and threats and then drowns trying to interpret that persons mappings. While that's happening I can find 5 other someones and suddenly I have 6 addresses all of which essentially ephemerally link to my system. Someone else does that for their mapping system and you get to Dijkstra levels of working out how to block connections.

After like 3 levels of middlemen even centralized authorities just struggle to do the actual work of blocking, outside of just issuing the order.
