Yes but food for example is a thing markets work great on, there's pricing transparency and it's easy to switch suppliers and shop for better prices. The same cannot be said for healthcare for example where it's pretty clear markets fail precisely because it's nigh impossible to do those things. Central planning works well when markets can't. No one is going to shop for the best emergency room price while having a heart attack, nor can you even get transparent pricing from hospitals; you can't know what you owe until after you've have the services performed because they can't know up front what services you're going to require.
