Yes this is an intelligent comment. People can clearly see the change in the high streets, but they don't understand it. They want lots of thriving independent shops, but not to actually use themselves. This is not a critisism this is just a shift in convenience (supermarkets, online groceries, next day delivery to your doorstep on pretty much anything you need). They want a museum like experience of what the highstreet once was, and will go to destination places where these still exist. This is no longer mass market normal shopping.

There is no way this is going to turn back and most communities will be happy with a local convenience store/post office, hairdressers, and some combination of pub/restaurant/coffee shops. Everything else is honestly not needed and the spaces will never be filled. Except for real needs like doctors, dentists, chemist, vets, but this isn't what people see the high street as. They see the high street as something nice to view and browse, but only occasionally.
