And that's why the borders exist in the first place. The point of money is not wealth, but wealth disparity. Money gives you power over those with less, and borders help enforce that disparity. The poverty is a feature, not a bug.
Borders must be abolished to sustain the capacity for life to exist, not to aid in the continuation of capitalism. Capitalism is a reactionary death cult maintained by hyper-exploitating all forms of life.
Even Marx thought that capitalism was an improvement over earlier systems, and he might be correct. But like religion - which helped people cooperate at larger scales than a tribe - it has reached a point where the evils that it inflicts on the world far outweigh any past benefits.
