That’s an interesting take… The border might be “artificial” in terms of land, but in terms of culture and quality of life I think your opinion is a bit… extreme. Like, if you had to personally host an economic migrant from a very poor country I don’t think your resolve would hold. It’s one of those things that sounds nice on paper but really isn’t once implemented.

Consider, for example, that countries on opposite ends of the of the political spectrum and economy agree that they must have control over their borders to some extent. Either to keep people in or to keep people out. Do you honestly believe that communism, democracy, or [insert your preferred system here] can work if you allow millions of people who hate it into your country? Your opinion does not seem compatible with a functional society.
