I didn't argue that people cannot work together at scale. My argument, admittedly heavyhanded, is that organizing this work based on altruism does not work. It may work here and there, for a period of time, but it is not sustainable. Organizations that work are ones where people are paid for the work they do, not ones that pay people regardless of the work they do.

By the way, anti-ethical does not mean unethical. It means contrary to, in this case, contrary to human nature. I did not write that communes were anti-ethical. I wrote that they were anti-ethical to human nature, meaning they are contrary to human nature.

There's nothing unethical about voluntary communes, but there's plenty unethical about forcible ones.
