How can someone justly acquire unowned property under Robert Nozick’s entitlement theory?

Under Robert Nozick’s entitlement theory, an individual can justly acquire unowned property through the principle of appropriation, provided that this acquisition does not disadvantage others.1

This is one of three legitimate means Nozick identifies for the acquisition of holdings, which form the basis of his theory of justice. The other two methods include the voluntary transfer of ownership from one person to another and the rectification of past injustices regarding the acquisition or transfer of property. According to Nozick, if a distribution of holdings arises entirely through these legitimate, historical transactions, it is considered just, regardless of how unequal the resulting distribution may be.1
