People vastly overestimate the ability of central planners to improve on the independent action of diverse individuals. What I've learned watching regulators is that they almost always make things worse. If regulators did nothing, the self-correcting mechanisms of the market would mitigate most problems with more finesse. And less cost.
Liberalism had come to mean spending more on everything-speech police, failed poverty programs that reward dependence, a bigger nanny state telling us we cannot eat fatty foods, workplace roles that stifle opportunity, and absurd environmental regulations.
The market performs miracles so routinely that we take it for granted. Supermarkets provide 30,000 choices at rock-bottom prices. We take it for granted that when we stick a piece of plastic in a wall, cash will come out; that when we give the same plastic to a stranger, he will rent us a car, and the next month, Visa will have the accounting correct to the penny. By contrast, "experts" in government can't even count the vote accurately.
Fraud will always exist. Enforcement of anti-fraud laws is a useful deterrent, but in the end there's no substitute for investor vigilance. Government regulations provide a false sense of security - and that's worth less than no sense of security at all.
What private property does is connect effort to reward, creating an incentive for people to produce for more. Then, if there's a free market, people will trade their surpluses to others for the things they lack. Mutual exchange for mutual benefit makes the community richer.
