(I do side-eye people who refer to westerners working illegally in the non-west as "digital nomads" while referring to non-westerners doing the same in the west as "illegals")
Do digital nomads have employers?
They likely are. You meet a few DNs here and there who work entirely through cryptocurrency, but everyone else gets paid through ordinary bank channels that bring tax obligations.
These days, rather than the Spanish Empire stripping South America of its gold and silver, it's individual workers emigrating to countries with a low cost of living to maximise their own personal wealth.

How exactly does this "exploit the New World's resources" given they will probably get less infrastructure than in their country of origin?
Apologies for not giving you a proper reply, I'm just about to go to sleep.
