Because the edge cases are well known to be horribly, poorly managed by individual finance. Because they instill a tremendous discrepancy on the propensity of individuals to thrive in given socioeconomic conditions, they are the exact kinds of things we should be doing our hardest to remove from strict capitalism.
The first world has already moved on to socialized medicine precisely for this reason. Besides health expenses, the circumstantial costs of differing degrees of needs satisfaction are much less varied - they effectively just become approximated by the regional costs of food and shelter.
Luxury goods are brought up because we are talking about after base needs are fulfilled, and predicate the discussion on the basis that, one, the US is barbaric in its lack of comprehensive medical access to its people, and two, the edge cases where money can still buy you better care once you migrate away from allocating medicine based on ability to pay rather than need are extremely rare, and while still being a problem, don't predicate the whole discussion.
Basically, anyone sanely arguing for any of the socialist principals around happiness thresholds or sane taxation are starting from the presumption that negative externalities of environment like health problems out of the control of the individual need to be collectively accounted for rather than individually, and to do otherwise - as is the case with Steve Jobs liver transplant - is unethical. Primarilly because while we may have a shortage of liver transfer candidates today, the fact that demand for liver transplants comes from having wealth rather than need for replacement livers is certainly stymieing research into growing livers for transplant, as is the case with most organs needed for transplants. The capitalistic nature of medicine and the predisposition of those in need of it to have the least to pay for it contributes to why we have dozens of viagra-esque medicines with billions going into research for whatever the billionaire class might want medically while essential research in edge problems, especially chronic lifelong debilitating diseases like Parkinsons, is crippled by a lack of profit potential because the sufferers are often destitute or dying.
