The article is devoted to the study of the concept of a sharing economy. The concepts of distribution and non-availability are used for thematization of the method of analyzing economic structures. Distributivity (a relationship arising in a shared-consumption economy) is interpreted as the essential characteristic of things that dictates the forms of social relations. A detailed definition of well-distributed things is proposed. The ability of things to act as distributed has both pragmatic appeal and special dynamics, which depends on the class to which the distributed thing belongs. Classes of distributive things are briefly described. Universal and individual classes are very rare, and a special, limited class of distributivity allows the formation of sharing networks. It is shown in what sense the right of exclusive ownership depends on the negative class of distributivity. The very property of distributed things not to decrease in sharing, undepletability, should be distinguished from the concept of a resource. The resource acts as a matter for the relative autonomy of economic relations, undepletability dictates the rules by which relations are built within the sharing network. It is shown in what sense the source of wealth in the economy of joint consumption relates to undepletability. The conditions under which the sharing forms of economic relations exhibit the undepletability of things are described as proximity, separation, and care.
