Yes, it intentionally breaks with human history, which has been largely built around and fought over borders for a really long time. What people argue is that it's not human nature but learned. We organize ourselves locally and in communities, there's nothing natural about patriotism and nation states.

I personally think they are correct in fundamental parts of their criciticism, but that doesn't make it a realistic goal work towards any time soon. What we can do is to question the premises we are trained to accept and to think critically about how we should structure our societies going forwards.

Arguing we can't abolish borders because of Russia and America is a bit like arguing nukes can't be abolished because of the need for nuclear deterrence. It might make some degree of sense as a practical argument, but not as a normative stance.
