 Theorists who persevere with the ‘bundle of rights’ analysis nevertheless present some sticks in the bundle as more important than others: the right to exclude is usually seen as the key to ownership, even if it is one among many other rights and legal relations that property comprises. It is the aspect of ownership that has the greatest impact on others (Waldron 1993). Other theorists are more skeptical about this. Katz 2008 and Dagan 2011 suggest that in our analysis of private property we should place less emphasis on the right to exclude and more on the owner’s power of agenda-setting so far as the use of a given resource is concerned. On any account, ‘exclusive use’ is a complex idea. Its implications vary from context to context and from object to object: we actually have a plurality of property arrangements, striking different balances between owners’ and others’ interests (Dagan 2013). In its most abstract terms, the right to exclude implies, first, that the owner is at liberty to use the object as he pleases (within a range of generally acceptable uses) without interference from others. Secondly, it implies that others have an obligation to refrain from using the object without the owner’s permission. The point about permission implies in turn that the owner has the power to license others to use her property. She may lend her automobile, rent her house, or grant a right of way over her land. The effect of this may be to create other property interests in the object, so that the various liberties, rights and powers of ownership are divided among several individuals.
