Except abandoned cities won't magically go back to some idyllic paradise. They're full of value (shelter, metals, art, etc) that someone is going to want to extract. And they're also full of lots of potentially dangerous stuff too. Dealing with broken cities will not be cheap, swift or easy. I have no ready solutions. But thinking that we can just walk away from them is only setting ourselves up for different problems down the timeline.
