I don't even know how this would work, but basically as a libertarian I started as against borders because they are government-created boundaries
Then I recognized that without borders it seemed difficult to decide who was and wasn't a citizen and that wasn't fair, and that it seemed like certain people in government wanted to bring in more people to get them to vote to destroy freedom, so actually the libertarian position would be for borders to protect freedom
However, now with covid we also see borders being used to prevent people from moving - some people have been stuck in countries they attempted to live in temporarily or were on vacation at, or haven't been able to visit countries because of border restrictions
The libertarian (ancap) position on borders is that private borders are fine (like, on land that a person owns, they can choose who can "immigrate" to it or not, or like private cities can decide who is allowed to visit)
So are any conservatives against borders or what do you think of this issue in light of recent developments?
You can't have a free lunch without putting a wall around it. Remove the welfare state and borders become a non issue. Immigration is a government program. Without the welfare state you'd only be able to survive if you assimilated, you know, like the first 200 years of American history.
And the ancap position would argue that there shouldn't be anyone to vote for in the first place, so there wouldn't be anything for immigrants to vote for when they arrived.
