Y'know, instead of illicit raves in residential buildings, I think you could have officially-sanctioned "public houses", or "pubs", where people could go to socialise. These would serve reasonably-priced alcoholic or non-alcoholic drinks, would provide a space free of irritating and intrusive television screens, would not permit any kind of gambling, and would occasionally feature live music by a full band, rather than one guy with a laptop computer playing along to dreary 1970s soft rock by the Eagles and/or James Taylor. Of course, there would also need to be inexpensive and efficient public transport to, from, and between these places. Call me mad, but I think a lot of people would like such a thing.
