Self-reliance is when you can contribute enough to society on your own to get the things required to live in return without hand-outs.
I think you've mistaken "not in debt" for "self-reliant".
The poster seems to express an affinity towards Objectivist thinking based on some other comments (I wouldn't assume an ideology they haven't overtly claimed.), but has a very narrow definition of what altruism is. I would argue that this is a problem, because objectivism and its usefulness to society depends almost entirely on how you think of altruism.
Proponents of the viewpoint in general are very dismissive of things like paying for the care of the diseased, even when there's a strong and perfectly reasonable objectivist argument that you should do so purely out of self-interest because of how diseases live and are spread.
