the right to own private property was unlimited as long as nobody took more than they could use without allowing any of their property to go to waste and that there were enough common resources of comparable quality available for others to create their own property. Locke did believe that some would be more "industrious and rational" than others and would amass more property, but believed this would not cause shortages. Though this system could work before the introduction of money, Marx argued in Theories of Surplus Value that Locke's system would break down and claimed money was a contradiction of the law of nature on which private property was founded.
