Whether it's too much to ask or not, depends on the people involved. Adults with busy lives still manage to show up for their child's evening activities once a week, to make that volunteer commitment of a few hours every weekend, et cetera.

Scheduling comes down to priorities. Unfortunately, a that hobby has no other benefit than to keep you happy, but requires several hours to do so, may not be something it's possible to prioritize, when compared to other commitments and the effects they have on a much larger number of people around us.That's life.
