It isn't harmful to people collecting rent for those Airbnbs. Or service workers who can demand higher salaries. Or local business that see increased sales. Or the government itself that can collect taxes on all of it. A large amount of foreign income being spent in a local economy may cause temporary disruptions to the status quo but is overall a good thing. It shouldn't really be a surprise that governments worldwide are encouraging it.
