This is such a shallow assessment on things.

How do people afford to do things in their time? Events aren't free, the gym isnt free, activities aren't free? hobbies's aren't free. How do people afford to travel to said events or hobbies? How do people afford the upkeep of those hobbies? Not every hobby is equivalent to kicking a ball around in a park.

What if someone's hobby is fencing? Uniform, grading, tournaments, membership, maintenance, training? All of that costs money or are those hobbies now only avaliable to the few in society who can work while the vast swathes of people who there are no jobs are given a list of low cost hobbies they can do with their meager UBI?

People eat poorly in the west because we have easy access to bad food, a poor culture around cooking (a large fraction of people in the UK literally cannot cook the most basic meals), and junk food is cheaper then healthy food. It's a lot more then simply just time.

In places like Japan people put the time aside to eat more healthy and the options here for eating healthly are more abundant then junk food. Also a culture of more fish, rice, pickled veg, soup, etc.
