 A fourth concern about the counter-intuitive nature of full self-ownership points out its restrictive implications. Full self-ownership might seem to condemn as wrongful even very minor infringements of the personal sphere, such as when tiny bits of pollution fall upon an unconsenting person. Prohibiting all acts that can lead to such minor infringements poses an unacceptable limit to our liberty. But from the point of view of self-ownership, there is no principled difference between minor infringements and major infringements. Thus, this objection goes, self-ownership theory must be rejected (Railton 2003; Sobel  2012).[1]
