The cynic would say that if their business model isn't viable in the legal framework that's just because they didn't scale fast enough. After all Uber and AirBnB have gotten away with a lot of illegal stuff. But yes, maybe a service such as this can't exist in our legal framework. Which on the internet likely just means that someone will launch a more shady version in a more favorable jurisdiction. Of course that shouldn't preclude us from shutting down this version if it turns out to be too harmful. But if the demand is there, finding a legal pathway to a responsibly managed version would be preferable (not that this one is perfectly managed by any means)
