Most Conservatives would certainly agree with a minimalist government, Vagabond, Heinlein occasionally wandered off into 'No-government' thinking, though. It's an idea popular with a certain particular strain of hard-over extreme Libertarian, the problem with it is it's a model with a very limited run-time before bad people start coalescing into groups to exploit it, and good people have to start coalesing into groups to fight them off, and pretty soon you'd end up right back at feudalism.
