You think most people wouldn’t become homeless if they spent less time working?
I did specify 'housing crisis aside', but yes. 40% of Americans own their own paid off home; most renting households still spend around 33% of income on rent. 67% of income, then, is spent on things other than not becoming homeless - do you want to speculate on what amount of that is actually necessary?
That is not the argument I was making. People can still desire more even under an Anarchist society, the difference is that anything more they want they either have to make themselves, make it collectively under a worker cooperative, or trade with another person with something they acquired by their own means or as the fruit of a cooperative effort.
But I never disputed any of that. The entire point originally raised was that people would still desire to do less work even if they had their needs fulfilled.
That ensures that no one can effectively exploit anyone else, or create a power imbalance with a hierarchy.
How does that follow? Some endeavors are more profitable than others. Hierarchies can be set up even without material differences (which, as we've established, certainly are not eradicated). Exploitation is often predicated not on material differences, but social manipulation, and result in material differences.
