I wonder where the people behind this think it will end? On the surface, this appears like a libertarian attempt to dethrone governments and other authorities from having control over internet content. But what we have seen time and time again is that these things follow a cycle so predicable its almost boring:

(a) technologists break free of control and invent libertarian paradise (b) criminals and other bad actors flock there (c) governments create laws and regulations that make it either illegal or practically so inconvenient to operate such services that nobody can do it any more

In practical terms, what exact plan do they have when Web3 becomes a giant cess pool of child porn and underground illegal gambling and drug trading? Do they really think governments are going to say "Oh well we can't do anything about these 'unstoppable' domains so I guess child porn is ok now?".

Do they understand that the inevitable actions taken by government to regain control will end up over-reaching - almost by definition. The more resistent the libertarian paradise is to control, the more blunt and severe the response is going to be in regaining it.

The worst thing is, when the over-reach happens, it doesn't just affect thelibertarians; it wrecks every other valid use of the technology. Witness the sun setting on legal encryption as governments steadily outlaw it around the world.
