Health care -is- a commodity because resources are limited. While private investment can, over time, increase the total amount of wealth when not hampered by undue regulation, at any given time the pool of available wealth is limited.

Any tax money spent on healthcare cannot, by definition, be spent on any other "social good." Borrowing, or printing money, merely pushes the debts forward onto our children. The Gods of the Copybook Headings, the rules of limited resources, remind us that despite good intentions, debts that cannot be repaid won't be and promises that cannot be kept will be broken. Failing to treat healthcare as a commodity ensures they won't.
