gollark: Clean water *from taps*? As opposed to by going to a shop or something.
gollark: Technically I just "need" 1500 calories in some ratio of nutrients, but I like to have somewhat more than this and also food I like, so "universal basic food" would be bad.
gollark: Internet connectivity? Transport?
gollark: You've said so, yes. Or implied so. Said now.
gollark: You're just defining things as public services though.
