Humans and animals enforce their borders since millennia.
The idea that borders are unimportant is very very recent. That is to say, its commie gobbledygook.

In English it's "have enforced their borders for millennia"; the phrase "since [length of time]" is almost always grammatically incorrect and a giveaway that someone's not a native English speaker.
Eg Iberian Peninsula (Reconquista and later): Foreign parties >10 armed men could not cross without permission between christians and muslims.
Chinese frontier zones, Scythians, Huns, Mongols, Turks etc all had similar rules. If you want to go back further, then Assyria, Egypt, Hittites, Greece had such limits.
Some nations, countries or groups, or other levels, did play with some of those mentioned ideas of less border control mechanisms in some ways or levels, also going back thousands of years.
Countries that were not successful with border control mechanisms, sometimes ceased to exist.
But there are many different levels and ways, and the whole topic is, to put it very mildly, extremely complex.
I'd say no-border cosmopolitanism is more of a classic liberalism thing.
There are many that think themselves "cosmopolitan", when it is a delusion and coping mechanism about being a parochial hicklib. A chip on their shoulder that makes them especially fervent acolytes of liberalism (as in: Obama flavoured, not the other kind), hoping it offsets their humble origins after moving to the big city, so folks won't get the idea that they are flyover country chuds that vote the wrong way.
A cosmopolitan, as in one that truly knows the different cultures and people of the world because he has deep first hand experience, or has read so much that it allows to draw some independent form of conclusion, is either a strong proponent of borders or a fool.
The core tenet that makes this communism-adjacent is the denial of differences: everyone is equal, "no one is illegal" etc pp. Ignorance of history and the nature of man is a must to take this position.
Tell us how you really feel, good grief.
> everyone is equal, "no one is illegal" etc
This but unironically.
This is not "how I feel" or my actual opinion of liberals in general. It is a certain archetype that I unfortunately know all too well.
> This but unironically.
You can just say you're a communist, you know. The core tenet will always be some appeal to equality, no matter how you like to describe yourself ("socialist", "liberal", "a decent heckin' human being" in Reddit speech or what have you).
This is the most incredible No-True-Scotsman fallacy I've ever read.
