But the article has another thread running through it, that of a life of no commitment and of self-indulgence. This is especially obvious when read while imagining someone with children, but it likewise applies to spouses, families, communities, etc. Human beings are intrinsically social animals. Human beings need societies in order to flourish. All societies are defined by a common good, and that common good is prior to the private good. In fact, the private good exits for the sake of the common good. Self-indulgence might appeal to the hedonistic, selfish person celebrated by our culture, but it doesn't produce happy people in the true sense of the word. It leaves us alienated. This is a reason why we're seeing skyrocketing rates of mental illness and all sorts of identity politics. Nature, when frustrated, reacts in pathological ways. The return of the repressed.
Unfortunately, liberalism (the Lockean philosophical tradition, not liberal institutions) is a defining feature of the modern West, and the US in particular. The habits of mind that liberalism insinuates affect all of us and misshape our intuitions. But liberalism is in a period of increasing crisis. It is not going to last that much longer as it is unsustainable. Liberalism purports to offer a middle ground between radical individualism and collectivism, but all it really gives us is a "diabolical synthesis of the two, a bureaucratically managed libertinism" (Feser 2008).
A life of ostensible "self-fulfillment" is a road to misery and emptiness.
