Fair enough. I do think that "equality is good" is the claim that would need to be justified if this were a formal debate, but I can give some more details on what I think.
Roughly, my feeling is that perfect equality is unstable, or at least enforcing it would cost a lot more than allowing for (limited) inequality. I don't think that perfectly free markets are desirable (or efficient) but I think that how do distribute resources in a way that maintains equality while also keeping the median wellbeing high (relative to other systems) is a huge ask.
