Regardless of how "basic" her needs are, she is not entitled to a man who meets those needs (or are they really wants rather than needs?).

Fortunately, as Debbie Weiss stated in the article, ...

...she has already found one who meets her needs, presumably voluntarily. So, why is she so concerned about the so-called "maturity" of the remaining members of the male population?

By characterizing men who do not conform to her expectations as "immature," Ms. Weiss is implying that those who do not meet her expectations are deficient and need to "grow up" by conforming to her expectations.
