Authorized users have both access and withdrawal rights, such as those which are acquired with the purchase of a fishing license or a firewood gathering permit from a national forest. The right to regulate use and improvements. The right to determine who has access and who can be excluded from using the property. Citizens of Swiss villages that possess and govern their own common property pastures and forests are proprietors in this sense. The right to sell or lease.
Owners possess all the rights of proprietors along with the right of alienation.
Private property falls under this category, though owners can also be governments or communities. We can see that there is more to property rights than ownership. Under some circumstances people have relatively limited rights, such as those of an authorized entrant or an authorized user. For example, someone with a valid fishing or hunting license is an authorized user with certain rights to harvest fish and game, while government owns the wildlife in a public trust capacity. Usufructuary rights refer to certain use and withdrawal rights granted to property that is owned by others.
