Intellectual Property Laws Violate the (Free) Market
It is definitively the market—and only the market—that determines who owns what. For example, when buying a car, the seller hands it over in exchange for money. Thus, through these peaceful and voluntary transactions, true and sole ownership is defined. If, for instance, the seller fails to deliver the car, the buyer will present the contract to a judge (ideally a private mediator) and demonstrate that he fulfilled his part of the agreement.
