 The broader point is that libertarians generally accept that individuals can carry out such acts of original acquisition. More precisely, they accept that individuals can acquire unowned goods unilaterally, without having to ask the consent of approval of other people, some governing body, or anything else. The argument for not needing the permission of others to use and appropriate the external world is relatively straightforward. The moral benefits of private ownership are important, and if there is a good justification for having a system of private property, it should be possible to derive a justification for acts that begin to bring about such rights as well. Any view that would require the consent of others, or some kind of government legitimation, creates barriers to acquisition and thus threatens these moral benefits (Van der Vossen 2009, 2015; Mack 2010).
