The market will follow its inceotives. You shape those incentives with laws. If you want a market that allows people to take risks, you do that by inventing the limit liability corporation not by telling people to be nice and to not pursue their debts unto their debtors' personal property. If you want a market that discourages monopoly you do that by regulating combination not by writing articles about how "good businessmen" don't act anticompetitively.
