Let’s concede the point: humans are inherently greedy and selfish.
But greed and selfishness are bad, right? We want less greed and selfishness in the world.
Given these two assumptions—humans are greedy, greed is bad—shouldn’t we architect society to explicitly disincentivize greed?
You’re preaching to the choir. “Concede the point” is a figure of speech which means the speaker is going explore an assumption despite not believing it themselves.
My point is that the whole “capitalism is the best economic system we know about because humans are greedy” argument is sophistry. It doesn't even make sense in the context of its own flawed premise.
