There's very few of us with a hard enough heart who'd say no to someone who asked for a glass of tap water, or to use the toilet. As a society advances other basic necessities should move into the common domain too. (And the wonderful thing about capitalism is it has driven down the real costs of most of these things to historically absurdly low prices eg a thrift store pants for $7 in the face of $15 minimum wage is cheap compared to history when it was normative to have only 2 sets of clothes)
[1]: I'm thinking like shared bedroom, thrift store clothes, rice + beans + costco, annual checkup + bare minimum health insurance, annual dental cleaning / bare minimum insurance, a mint mobile $15 a month cellphone plan, and a library card for entertainment and education. You're not thriving, and you're not a catastrophic burden on the system either.
