Have you tried purchasing health care before? It's not inexpensive. There's no way we could guarantee food, health care, and housing for everybody with no work requirement. Only a really stupid person would believe this could work.
Money is an artificial construct used by humans to facilitate trading their labor amongst each other in order to get what they need to survive.
Arguments about how expensive things are make no sense if we restructure our society where money is only half the equation. The labor required to provide food, health, and housing is incredibly small compared to the overall economy.
People want to be useful, and people want more than just a place to live and food to eat.
The real danger would be in creating a system that stifles the free market side of the economy and leaves people stuck in basic assistance hell with no way of working to improve their lives. Worrying about the costs of providing basic assistance to all is actually the least important bit.
You're really stupid.
