There's something to be said for this, but it doesn't work to just flip to the opposite extreme. As long as there are wealth inequities, then free-market supply-and-demand turns into the idea that anyone poor shall have nothing, not even the capacity to travel on streets or drink water. If they don't want to just up and die, they can get a loan to do these things and go into a cycle of indentured servitude for life.
The free market has never had any solution to such issues. Supply-and-demand works best when all the players have the same overall capacity to pay for things, and that's not how reality works out.
Societies prosper when efforts are made to make sure everyone has the foundations from which to build a productive life. That means health care, shelter, basic food and water, safety, capacity to get around (transportation of some sort), and access to information (education, libraries etc). If everyone has that stuff, they have the chance to add productivity to society rather than be a drain in the form of disease, crime, and so on.
