I think a key issue is that people that want to go the gym don't want it to be crowded. Under the current model, supposedly gyms rely on people paying memberships but not going. But also, the people that are actually there also want it to be well under capacity so they don't have to wait for equipment, etc. So even if you're really confident that you would go to the gym often enough to recoup your costs, would you want to go to a gym where everyone else has an extra motivation to go?
