I would be fine with just relaxing in public places like parks without actually having to interact with anyone, unless some people appear to share interests.
Sadly, safe, clean public places seem to be an exception rather than the norm in the world at large, at least from what little I've seen of it.
So we go back inside enclosures that are commercial establishments (coffeehouses, restaurants etc.) in order to be around other people, but interacting with other patrons there is kind of a social taboo.
From my time on the planet I can only think of video game arcades from my childhood as the best examples of places where people got together to have safe fun and often interacted with each other out of choice and had even more fun in doing so.
