It's not really an ad hominem. I took it more as the reasoning in "What Money Can't Buy: The Moral Limits of Markets."
Ok. It sounded pretty harsh over here. Regarding markets: they are only the sum of the people that constitute them. Not all reasons or incentives for actions in a market have to be monetary. IOW: if something is of value to people, it will usually be done. If that doesn't happen, usually people say they want something, but do not really care that much.
One is also in Predictably Irrational: in short parents were always late picking up the kids from day care. The day care decided to issue a fine for late parents. The unintended consequences of this were that the parents were way more late on average because they felt they were paying for it. It switched the system from one based on social norms to market norms.
At ball games everyone used to be forced into the same shitty seats. Now the well to do get a pass and have luxury seats with better food and views. Instead of fostering community it further alienates the rich and the poor. This leads to a filter bubble of sorts that prevents both groups from empathizing with each other.
Same with courts and the legal system, fasttrak lanes, free shows put on that have secondary markets.
