This all assumes it's the locals and not wealthy migrants that bought a shit ton of real estate and are squeezing the investment for what it's worth till some politician grows a pair. AirBNB is also a foreing wealthy company, it's part of the problem because it used tech to evade regulations that protected against precisely what people are complaining about.

AirBNB's CEO should be brought behind the shed and sent to the far away farm.

Edit: Also, good luck regulating US big tech. The US started a proxy war to have the entire EU by the balls, smaller countries alone have exactly 0 chance.
