Borders are relatively open now. Property owners, in a more libertarian world, would have a lot more Rights/resources to protect their land than they currently do.
Get rid of the entitlement/wealth redistribution crap we give illegals now and the ones still coming here are the ones who want to BE Americans...
Libertarians have a simple solution for just about every social, economic and political problem: legalize it.
But their utilitarian approach to problem-solving is neither rule nor act utilitarianism: If a problem comes around, they whip it by saying, “Let’s pretend it really isn’t a problem. If we make it legal, then it goes away.”
Stroke of the pen, law of the land. Pretty cool, huh? Sure, if you’re into OA-style anarchy.

One of the things Id like to see is getting rid of property taxes once the property is owned, in some way. Maybe an upfront tax or something. But to pay taxes on a piece of property that you have paid off means that the government is the property owner.
