Another angle of philosophical attack is to say that we rarely hold rights to nature or to life. We can copyright a photograph we take of a forest - but not the forest. Wrong premises inevitably lead to wrong conclusions. We often own natural objects and manifestations, including those related to human life directly. And people do own forests and rivers and the specific views of sunsets.
Some scholars raise the issues of exclusivity and scarcity as the precursors of property rights.
True but not relevant. In other words, exclusivity and scarcity do not constitute property rights or even lead to their establishment. On the contrary, it is surprisingly easy to think of numerous exceptions to a purported natural right of single access to one's brain. There is one hidden assumption, though, in both the movie and this article. It is that mind and brain are one.
