We must work to build an inter[dark]net which ideally fully divorces the user from the government and laws of the country the user is physically in (unless the user leaks his dox).
Law and Govs are not so bad that we should get rid of it. They do add value to society compared to a fully lawless anarchic community/tools/etc. There is a place where freedom does have to stop and trespassing that frontier will have consequences.
We don't need to through all our laws and Gov (especially in Western countries where really it's not so bad). But instead, we need better law, law enforcement, etc... The key part is it's up to us to fight for it.
Think it depends on how large you want your communities to be. It should be fine until some 200 people.
In the end, the real service social networks offer is moderation.
