> so that people can go to church more, and church is healthy. Really? That's highly debatable, and obviously another power structure which is also old fashioned

This one is so debatable because the definition and theological implications of Church 'healthiness' depend upon many different variables and can differ subtly across all Churches.

Church isn't a 'power structure' though. It relies on voluntary participation. You can walk out of Church whenever you want.

Doing what you want tends to be quite narrow, hedonistic and unsatisfying in the end. It's easier to make the argument for free time from higher principles.
