total open borders...because “anyone should be able to cross the border regardless of whether the government approves”
To be fair many Libertarians don’t support open borders as long as we have a welfare state (for obvious reasons).
Saying that Libertarians support open borders is like saying Republicans support endless regime change wars.
Yes, there are some who do and some who don’t but most importantly, the ones who don’t are currently driving the party.
Look up the Mises Caucus and Dave Smith. They are now setting the agenda of the LP and it is not open border at all. And not just from a practical standpoint. On YouTube there are hours of theoretical and philosophical debates around the issue among LP members.
