Here's an interesting idea - get a whole bunch of committed libertarians and put them in one place to create a sort of libertarian homeland. That's what the Free State Project is about. Basically, they are looking for about 20000 people who will commit to move to New Hampshire where they will uphold libertarian principles. New Hampshire was chosen because it has no state income tax or state sales tax and with a motto "Live Free or Die", it's bound to be libertarian leaning. While I question whether it will make a difference, I do see it as an important step in libertarian activism.
Large governments don't work. Give a man power and he will abuse it. There are no ifs about it. My hat goes off to the Free State Project.
