be owned and that ownership of IP amount to an illegitimate claim of ownership over that which enters another's mind that cannot be removed or controlled without violation of the non-aggression axiom. Pro-IP libertarians of the utilitarian tradition say that IP maximizes innovation while anti-IP libertarians of the selfsame persuasion say that it causes shortages of innovation. This latter view holds that IP is a euphemism for intellectual protectionism and should be abolished altogether. Land ownership Following political economist and social reformer Henry George's philosophy of classical liberalism known as Georgism and the single-tax movement of activists who supported it (see also the single tax), some free-market centrists and non-socialist left-libertarians known as geolibertarians argue that because land is not the product of human labor and it is inelastic in supply and essential for life and wealth creation, the market rental value of land should properly be considered commons. They interpret the Lockean proviso and the law of equal liberty to mean that exclusive land ownership beyond one's equal share of aggregate land value necessarily restricts the freedom of others to access natural space and resources. In order to promote freedom and minimize waste, they argue that absent improvements individuals should surrender the rental value of the land to which they hold legal title to the community as a subscription fee for the privilege to exclude others from the site. Since geolibertarians wish to limit the influence of government, they would have this revenue fund a universal basic income or citizen's dividend which would also function as a social safety net to replace the existing welfare system. Based on David Ricardo's law of rent, they further argue that this tax shift would serve to boost wages. LGBT rights In general, libertarians oppose laws that limit the sexual freedom of adults. However, there are some more niche schools of libertarianism that oppose these things, for example Hans Herman Hoppe. Limited government Libertarians differ on whether any government at all is desirable. Some favor the existence of governments and see them as civilly necessary while others favor stateless societies and view the state as being undesirable, unnecessary and harmful, if not intrinsically evil. Supporters of limited libertarian government or a night watchman state argue that placing all defense and courts under private control, regulated only by market demand, is an inherent miscarriage of justice because justice would be bought and sold as
