It might give you warm fuzzies to think that every person has a "right" to food, water, shelter, and medical care. However, if providing those things to those people who are not making enough money (for whatever reason) requires taking the money (ei: through taxes/theft) of someone who earned it honestly, they cannot be considered universal rights.
Restated: if some so-called "right" requires violating someone else's person or using coercion (or threat of force) to take their rightfully earned property in order to be honored, it is *NOT* a right.
@chrisrushton - You seem to think that in a world without government we wouldn't have services. If there is a demand for a service, and some person (like you!) could make money providing it, some entrepreneur (like you!) would start a new business providing that service. We wouldn't exist in some sort of backward, pre-industrial backwater; we'd have many companies competing with each other to provide goods and services. Think what would happen to the price of healthcare services if that industry were more like the computer industry, where there's lots of competition and CPUs keep getting faster, video cards get more more advanced, and computers are becoming more and more powerful for the same (or a lower) price.
All products and services could be as competitive as the computer hardware industry. We'd have lots and lots of options, both in price and quality, in all kinds of products and services, even those currently provided by government theft.
