the power of the communist project is not that socialized medicine/free public transit/education/housing etc are actually more efficient and profitable if you do the math. it's in the story communism proposes: of a world unbound from the profit motive and its inequities, where people of all races, genders, and abilities possess equal unconditional dignity of life and labor within a society that exists by all of us, for all of us.
arguing anything less is a compromise to the fascists
it is by existence that we set the stage
but by non-existence that we have utility
