The US is the only odd one out in the first-world for healthcare, so we'll leave that aside (most people are covered through their employer, but many people aren't)

Everyone eats in the US. The tweaker on the corner eats. People can acquire food through a dozen different institutions like charities, soup kitchens, the church, etc. I don't see how a system that would coerce everyone to rely on fixed-number rations is meaningfully superior. At best the argument seems to be "spare someone the indignity of getting free food, by forcing everyone to get free food"

Housing is part-way. Homelessness scales with cost of housing, given the data. There are mediating services like shelters and low-income housing. It's not enough but it's not nothing. The solution is to do as cities do where cost is better: build more, enact zoning reform.
