I agree with this, but so few people seem to like it. International travel is such a luxury and costs so much carbon. It's my goto example of something I would outlaw since it doesn't affect me, and there's no "real" reason for it. Of course, my libertarian sensibilities don't let me actually advocate for it, but I think about it when people want to outlaw marijuana, abortion, drinking, cars, guns, or whatever activity people other than themselves want to participate in. It's too easy to see the costs and not the benefits when it's someone else's activity. But I really do think we'd be better off of more people voluntarily explored around their own home rather than taking far off vacations. Having lived in several countries and traveled to many more in my younger days (yes, I know, I'm a hypocrite), I don't find short travel visits to really help understand other cultures in any meaningful way like people like to claim. Extended visits or living there for several months or years does non-trivially change your perspective, though. As long as the place is substantially different and you make real connections with people.
