If Times Square is the only public space you can think of, you're either unimaginative or arguing in bad faith. Try Central Park maybe?

I have an axe to grind about interaction-free delivery services, but it's a different debate. Public spaces are for when you intend to see other people.

Public spaces as I've experienced them are much better than malls. For one thing they're outside. It's not easy to be outside for many city dwellers. They're also a place where you're not expected to spend money. You can bring your own food, drinks and entertainment. You can do nothing at all and not be perceived as a threat. You aren't screaming over the noise of car traffic. The silence is a revelation when you experience it for the first time.

I spent my summer in public spaces. I miss them dearly when I travel to concrete jungles and sleepy suburbias.
