The French government tried to do something similar a few weeks ago; as, among others, booksellers are closed down and were complaining about the same thing, they've ordered supermarkets to close off the parts of the store that sold books and "other non necessary items". Though it's been implemented chaotically, what's closed off tends to change from one supermarket to another and there are not nearly enough control.

However, it appears that when you do that, people just order that shit online and Amazon benefits instead.
