“It seems to me that its main point is that government should not be coercive regarding economic activity.”
Even the most extreme supporters of laissez-faire — other than Rand — agreed that there needs to be some coercion. Hayek supported mandatory health insurance and Friedman a negative income tax.
In any case, Torah law is FAR more coercive. Leket, Peah, Shich’chah, Shmita, Yovel, Trumah, Maasrot, the prohibition of Geneivat Daat, the prohibition of Ona’a, the prohibition of Ribbit, no provision for limited liability, no provision for securitization of debt — the Torah financial system is so different from what we in the capitalist world today are used to that we find it hard to imagine.
