Issue here, imo is also the supervision requirement. The kids are not allowed to go outside independently without parent until they are basically teenagers.

Parents have stuff to do and also nothing to do on playground. So they stop taking kids there once those are over toddler age and won't destroy house put of sheer energy. Playgrouds are boring and 9-11 years old truly have nothing to do there without friends group.

So 6-10 years old kids are rarely outside. They know how to have fun at home and school, but they have no community in park and don't know games. Then they are 14-16 and everyone is like "why don't they go outside? there is basketball court". But shooting balls alone is fun for like two days and they don't known to have fun there.
