WRT the decline with age, I've always felt like a lot of it is 'ego based', for lack of better terms. I've found that as time goes on, people are far more concerned with doing things by the book, projecting an image, etc. rather than just 'being', enjoying life in the moment, doing things just because. I've certainly been guilty of this to some extent because it seems impossible to avoid. Personal anecdote: At age 16…
I have some anecdotal perspective to offer in regards to where we tend to hang out when we’re young (reasons vary for us aged folk). One of the big reasons we end up at parks, or bus stops, or 7-11 parking lots, or wherever as teenagers is because we generally don't have the financial or social independence to go anywhere else to enjoy ourselves without the "burden" of adults.

A restaurant is a place where speaking more loudly than a certain amount will earn you ire from others. You're surrounded by other groups that aren't your group. There's a prescribed format.

I hate restaurants, and cinemas, and cafes, and stuff. Just give me a roof and we'll make the fun. But the roof doesn't exist, because as a society, we decided that capitalism and the building of private castles is how it's going to work. Railing against that as an individual is terribly hard.
The problem with it, is that if we decide as a society that these paid, gated experiences are how we're going to socialise, then everyone who doesn't work hard enough is excluded. That's how we get things like socio-economic groups. If you socialise in restaurants, then your friend circle reduces to the people who can afford to socialise in restaurants.
If it's non-deliberate, then it's sad. If it is deliberate, then it's the 'ego thing' that I tried to speak of in the first post - it's about us not realising that we are humanity, we don't need to battle each other and assert dominance, we can just be, you know? Individual, yes, but one, too.
We need public spaces and gatherings because otherwise the ultimate endgame is that people retreat into ever-smaller niche groups until we just sit on our own.
