Imagine apartments built into what used to be department stores, (Oh, you’re JC Penny 203? I’m at Sears 106). Get those old arcades up and running. Set up meal stations at the food court. Once people actually live there, stores will start to move back in.
If I’m unable to finish my life in my own home, that doesn’t sound like a terrible option.
malls were a place to just exist
Not really. Malls existed because enough of the people who went there were spending enough money to make them profitable.
Yes it was permissible to go to a mall and not spend any money, and a lot of people did just that, but that doesn’t mean malls did not require most people to be spending money.
