Except it won't work. Freedom of speech limited to well composed political speech is not what it sounds. Modern day China(PRC) guarantees in the constitution that kind of freedom of speech, just they label any speeches that isn't conformant to current Party statements to be terrorism conspiracy. Even Nazi Germany had that constitutional clauses.

It just starts from porn and ends in gas chambers. And in the middle is freedom limited to "meaningful" contents and activities. If you looked up and compared state of freedom of speech, CSAM/CP regulation, internet censorship, especially authority intervention, crime rate, and standpoint on democracy-totalitarian axis for various random nations, it should all line up well against each others.
