You may be missing the point that these activities can potentially be in your backyard if you don’t live in an apartment. My kids can swim or play privately in my backyard and I still have plenty of space for my gardening hobby, bbq-ing with extended family, various outdoor games, or just hanging out watching tv in the backyard. I’ve known people who have basketball, tennis, or pickle ball courts in their backyard. Outside of very specific museums or live music/sports venues I can’t think of any activity that is available in a dense city that isn’t in my suburban neighborhood.
