I had to stop listening to this video after a while. The speaker works hard to reinterpret history to justify his claims--so hard that his talk devolves into a word salad of contradictions. There are so many errors committed during this talk, I'm not sure where to start.
His premise that violence occurs solely because of economic disparity is pure foolishness. Listen to news reports in your local area, and you'll quickly find evidence against this. The shooter in Las Vegas from a couple of weeks ago was a millionaire. He had the means to buy an armory of very expensive assault rifles. He had the ability to quit work and spend his days as a full time gambler. And he decided to shoot hundreds of rounds into an audience gathered for an outdoor concert. Where is the morality in that?
There is no such thing as a free market. Markets are utterly dependent upon a system of laws defining everything from property rights, enforceable business transactions, fraud, currency as a means of exchange, bank deposits.
Further, market forces create unequal relationships of power. If a company holds a patent, and it's the only supplier of a product, it can use (and abuse) its economic power to gouge consumers. Yet, when someone offers their expertise and talent in the labor market, they experience the opposite effect: there are no patents protecting their position. They must compete with scores of others, similarly situated. They are utterly powerless to set the price for the services they supply.
Power corrupts. Absolute power corrupts absolutely. The libertarian apparently is quite satisfied allowing economic power to gather and multiply, even to the detriment of the rest of society. A better approach is to enact additional laws preventing such power from spiraling out of control.
