i conversed with an acquaintance once about the wall. the acquaintance stated that she was against border walls and felt that they were unnecessary. i responded that it followed that she was therefore against laws. i would have continued that this followed since lack of border walls precludes laws from being enforced in a consistent manner, and inconsistent enforcement of laws is often worse than any laws at all since inconsistent enforcement leads to government corruption. the acquaintance became very upset and said something to shut down the conversation entirely. (the acquaintance professed to be a libertarian. i am aware that libertarians are frequently against borders.)
One platform of the Libertarian Party is something like “free flow of goods and people across borders”. IOW no border controls of any kind at all.
