Whatever fills the void for people. ie: instead of bowling leagues, people watch TV or play video games. It's arguably a worse product because it doesn't fulfill the socialization or exercise needs of people, but it does fill the same block of time.
I guess it’s worse in the sense of providing health benefits, but it’s better in the sense that more people would freely choose it if given the choice.
It’s the same as junk food, people will freely choose it over healthier options.
Basically, products on the free market optimize for what people prefer to buy, and people’s preferences are shaped by evolution to a world in which physical rest and high-calorie foods were scarce. This makes us mismatched to the modern landscape.
