Free market doesn't work on human necessities. We need a planned economy when it comes to things people require to survive

Anarchists don’t have planned economies

Okay I don't know.

But we can't just let the free market decide what is done with human necessities. We need to ensure that all people always get what they need

The free market allows everyone to get exactly what they need. Is your fairytale society going to give me the bolt action .30-06 with optics and a suppressor that I need?

A planned economy always results in shortages. We tried it many times with price controls on food and we always ended up with shortages.
