Years ago when I was in New York often, I had the idea to make a paid bathroom app, with a bit of a luxury twist. You’d pay $30 or whatever a month to have access to 40+ well-designed bathrooms across the city. The idea was that we’d own and operate these, and they’d be extremely well-designed, have beautiful tile interiors, come with a variety of hygiene products, water bottles, and so on.
I still think it could work, but over time I began to dislike the idea, as it would have been yet another example of the public commons essentially being eroded and replaced with a privatized paid system. Not that NYC public bathrooms are even remotely nice to begin with… but I think a better solution would be less deliberately exclusionary. Then again, what could be more NYC than the idea of paying money to get better things?
