Sounds nice on surface, but on a deeper level it sounds quite delusional (or deliberately misleading) assuming his plan does not rely on removal of all states to make a one world govt:
Suppose I have citizenship in Australia, I work in USA and I post something while being in Finland on vacation. Whose laws are supposed to govern this post?
There will of course be posts that give Twitter lots of headache because of differing laws, and what they will soon realize that even when they do a great job of juggling these things
"These new rules are designed to protect internet users" I suppose there are simpletons who think that, but of course the opposite will be the reality, it will stifle free speech.
