What this idiot is trying to do is justify the welfare state as ensuring basic human rights.
Note the use of the word “should” in the essay. Probably without knowing it, the author has implicitly assumed what he is trying to disprove; the moment he uses words like “should” or “ought” in discussing rights, he has assumed the pre-existence of a right.
Unless he does this, he has no basis for asserting that his “hierarchy of rights” is preferable to, say, Jack London’s “law of club and fang” — oppress the weak and obey the strong (which is observed in nature far more often than his hierarchy).
