There is already an ecosystem of for-profit social events in European cities (and probably elsewhere) profiting off people's desire to meet up with other human beings when social opportunies have shrunk. Once has seen this on e.g. Meetup.com or Facebook for years now, where bot profiles are used to swell event-signup numbers so people think they will meet more people. Indeed, with the enshittification of Meetup, the only forces that prosper on that site are for-profit ones.
