without taxes there is no society. without society you're very likely to experience actual theft and actual gun barrels, but very little services.

I hear there's no taxes in Somalia and it's only a plane ride away.

You are wrong about one thing. It is the people who should actively seek solutions to poverty, crime and war. By giving that power to politicians, you ensure that there will, in fact, be more laws passed and no solutions found. People need to stand up and take the responsibility back from the government and quit relying on that government for their every need and whim.

So what exactly happens in the absence of government? Or a Representative Democracy? Would abusive, rich, powerful individuals just disappear?

"The auto lobby (carmakers, insurance companies, aaa etc) do their best to ensure that there's insufficient public transit/public transit of insufficient quality, forcing people to buy cars to get around..."

Care to give specifics on how these industries you just named actively ensure there isn't sufficient public transportation?
