What laws exist against a 5ghz ubiquity mesh network?
That easy: make you liable for what people do on your network. Make it hard to register as an official network provider that would forfeit some of the liability.
(AFAIR, in Germany there are some changes now, but it's a good example how Internet sharing is made difficult for anyone without a large legal department.)
I'm not sure what to say to this. I don't think that these challenges make my opinion wrong or invalid. They make me sad, and I'd like to fight against such challenges. But from an idealistic point of view, I don't think that they raise a fundamental problem with my belief in "community networks", merely a legal one which might be able to be fixed through protest and civil-disobedience, and all else failing, revolution (I guess you have to leave revolution on the table, despite the bad results revolutions have had in recent years, if democracy in your country really doesn't work at all).
