Comment on economic order and the invisible hand:
There is no such thing as a ‘free market’. All markets operate according to rules.
The realists would argue that rules are needed to protect consumers and individuals from liar, cheats, scam artists and those who willfully impose their external costs on the rest of us. The Libertarians prefer a caveat emptor approach.
Certainly, everyone cannot be protected from everything. However, turning the sharks loose in the baby pool has high social costs.
