Decentralised systems have a horrible truth: they tend not to optimize for the problem they are set up for but for the thing that creates the greatest feedback loop. In case of a healthcare system inside a capitalist society, the system will optimise for profit maximalisation, this automatically means that a large group is cut out of care because: 1) they require too much care 2) they cannot bring enough money to the table

Its a simple fact of how markets work. A free market is just an ideal, just like democracy, open borders and justice. It is not some law of the universe. In fact: countries that profit most of their markets are countries that highly regulate them. These countries include the US, China, South Korea, Zwitserland, Norway and Dubai. But not: Mozambique, Venezuela, Sudan, Russia, Haïti. <-- these countries dont have functioning markets because there is too much unregulated behavior, too much corruption.
