As you've stated, a society will break down if there is no enforcement of rights as it is equivalent to them not existing. This is because the government is the sole definer of rights, and they only exist because the government has the will and ability to enforce them.
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.
This may be different under other governments depending on how rights are defined in their society, but in the US it is absolutely not the case.
