Well, they could still be (at the very least) prohibited from operating in your country.
Sadly, most of these services (Airbnb, Uber) were also illegal here in the US, but for "some reason" (aka lots and lots of $$$), no one ever bothered enforcement against them. Eventually they spent enough money on bribes^H^H^H^H^H^H lobbying to legalize themselves.
(Then, of course, at least in the case of Uber and friends, once they were established they quietly raised prices and reduced driver income, which were the very reasons the short-sighted public liked them so much.)
