mutualist wikiP page:
Mutualists reject Anarcho-Capitalist land ownership on the basis that it is merely re-arranging twigs.....if you make even a minor superficial improvement and can manage to convince yourself that it improves the value of the land, like planting a tree or making a pond, that its ridiculous to claim all of the surrounding area as your dominion by that alone....instead, use would define occupancy, and the capitalist class would lose their holdings to the underclass, which mutualists see as a positive step towards free market socialism.
another wikipedia page:
"Mutualism is an enemy of individual liberty and a free market, though not to degree that "anarcho"-communism is their enemy. This is because when it concerns land, houses, and buildings, it does not recognize a right of an individual to own the product of his labor and trade. If a person transforms fresh land through labor, and therefore justly appropriates it as his own, mutualists believe that if he does not continue to use it then he is acting criminally if he protects it from being taken by someone else to use. The same policy holds for houses and buildings. Thus, mutualism condones a person being deprived of the product of his labor. And, if that original appropriator sells the land or buildings instead and the purchaser chooses not to use them, he is seen as a criminal if he prevents others from using them. Mutualists believe it is fine for a person to come along, and take over that property by using it and therefore deprive the purchaser of what he purchased. Perversely, mutualists see these things that someone labored to produce or spent their hard-earned money on to purchase as being by fair game for anyone who wishes to take them for use, and he who defends his purchases from being expropriated as the criminal. Though mutualism recognizes a right to own product of labor and trade in other things, it denies private property in these and is therefore an enemy of liberty and not thoroughly anarchist." this quotation was attributed to "anarcho-capitalism" on wikipedia, so it seems to be the opinion of at least one person who calls themselves an @cap...
