The same can be said about illegal immigrants and temporary visa holders in the United States. An H1B worker pays taxes, pays into social security, etc, but isn't going to get a penny back out of it.
And yet, for some reason, a lot of people really dislike[1] H1Bs...
[1] Last election cycle, I've received a beautiful election pamphlet from a frothing-at-the-mouth state politician-want-to-be who spent most of his 250 words assuring me that H1Bs are robbing the country by mooching all of its services while not paying any taxes. He, uh, got 40% of the vote.
There's a glaring difference between a digital nomad working remotely and someone on an H1B or an illegal immigrant - the digital nomad isn't participating in the local labour market. Increasing the labour supply (which most assume would decrease the price) is the major complaint people who dislike H1Bs/illegal immigrants. A digital nomad isn't competing with the people he lives near for scarce jobs, so that complaint doesn't apply.
This is the typical communist/labour style answer which ignores that todays mobile work force is not just a body in a geography. An employee past about 5 years experience is essentially unique when observed across the many variables (education, years of experience with each specific tool, industry/domain experience, soft skills etc). Just because a capable expat employee happens to presently be located in Costa Rica, doesnt mean a capable Costa Rican can be found. The most valuable people in the workforce are not cogs.
There's no reason it couldn't be employing a local, but there are an awful lot of reasons it wouldn't. No locals applying chief among them. If the company was explicitly not hiring anyone from Costa Rica, sure, that would be one thing. If the best candidate happened to not be Costa Rican, that's something else entirely.
