Only if being “entitled to the fruits of labor” does not preclude the state (or any state-like entity, don’t even start with me) from seizing and/or arbitrating the value of that fruit. If that’s the case, what is the value of the so-called entitlement?

The reason private property is vital to a just society is that we do not know the ultimate purpose of society. We can not even estimate the size of the universe; claiming to understand the role of mankind without knowing its position in the cosmos is like claiming to understand a blood cell with no knowledge of the circulatory system. We all have exactly the same right and cause to determine the purposes of our own lives. Different life goals lead to different evaluations of goods and services. I do not eat flesh, listen to K-pop, or ski. To appropriate the value of my labor for the benefit of these systems for which I have no use is a violation of my natural right to determine the purpose of my own life. To phrase it collectively, it is a violation of our equal rights to determine the purposes of our own lives.
