I think some people are confusing the challenge to capitalism as a challenge to division of labor, exchange of goods or other fundamental concepts. This is not our challenge, these are essential to a functioning society.
I'm certainly under no such delusions. As you say, unless we plan on giving up on civilization altogether, these functions must happen. The question is whether they'll happen via voluntary interaction, or state coercion.
Again, if you're simply saying that there are people gaining unearned wealth through illicit means, I agree and I fully support any efforts to stop them. But that doesn't seem to be where you're headed.
