It would also effectively mean that every region in the world would have to have the same laws.
Take Canada and the US. Very similar culturally, very similar economically, but some pretty important differences in human welfare. Like, every Canadian resident pays taxes to support a healthcare system, and if you need healthcare it’s free.
If you eliminated the US/Canadian border, people could live in the US where taxes are cheaper until they had a serious illness, then they could move to Canada to get free treatment whenever necessary, moving back as soon as the treatment was done. That obviously wouldn’t work well.
The only ways to make that work are either to eliminate the border, and have both regions have exactly the same healthcare system, or keep the border and allow both to have different systems.
