In the USA, law isn't only defined by statute, it's also defined by the courts through case law.
The courts in the USA have some doctrines like "substantive due process" that say at least sometimes the law will look also at real rights that people can actually exercise, and not just paper rights.
> Neither housing nor water are human rights in the US because they, as the commenter stated, require you infringe on someone else's private property (resources, time) to provide them.
And yet as a matter of inevitable biology, every other right derives from access to water. A person without water lacks all other rights and all capacity for exercise of any right (e.g. speech).
