Where I live, we don't have pay toilets, but when I was on vacation last I thought they were great. I was happy to pay a little bit for a clean bathroom instead of having to go at a coffee shop or restaurant. Stallman has a point, but it's easily addressable. The government could give the indigent vouchers to use the pay toilets. I'd even be happy to pay more to use the bathrooms to subsidize such a program.

Btw, here in France, we give a lot of free stuff to people in need, and we certainly won't allow this to be prohibited by European treaties. So yeah, providing free tickets for toilet is indeed a solution that can be considered.
