Why do people refuse to vote in Austrians when Austrian economics has never been tried before? Is it because some people don't realize that they don't have a right to take things from other people?
Many people might be concerned that real laissez-faire capitalism would prove to be a huge disaster and result, not in real freedom but in various kinds of dictatorship. People would have "de jure" freedom under the law while having "de facto" dictatorship in actuality. Basically, the wealthy class would end up owning all of the wealth and would be able to dictate to the lower classes in various ways. For example:
"If you want to keep your job here you need to be a member of the New Christian Church. I won't hire anyone who is not a member. Since my business is my private property the law allows me to do this."
So, to get and retain a job now you need to have the right religion, be the right color, have the right weight, refrain from premarital sex, etc.
What if all of the business owners got together and decided to blackball someone for submitting a political or religious editorial to the newspaper they disagreed with? What if they all decided to shun this person and refused to sell him goods and services such as groceries? What if the guy who owns the road (roads are privately owned) decides not to let him leave his driveway? If he backs off of his driveway onto the road he's now violated the road-owner's private property rights.
What would prevent the nation's population from exploding to 1 billion people once the billions of poor people around the world happily immigrate to the U.S. seeking the princely wage of $3/day?
You get the picture. Basically, real laissez-faire capitalism would end up transforming us into a third world country where perhaps 5% of the population would be rich with the rest living in poverty and dictatorship.
If we lived in a world of infinite resources--infinite land and water, etc.--so that everyone could easily obtain property and sustain themselves with it or start their own businesses then it might not work out too badly. People of your religion/philosophy could simply locate to an open area and begin to produce and trade amongst themselves. Unfortunately we live in a world of limited land and finite resources where huge conflicts of interest exist among rational men.
