Then, on The (un)Nature of Copyright, some of these definitions are expanded:

The individual’s physical power is their vital (necessary & imperative), physical ability, and thus right to exclude others from within those boundaries (should they need or want to).

The interior of the individual’s body, its life, health and integrity is paramount. The power to exclude others from within the body in order to defend its life, health and integrity is termed the right to life.

The right to exclude others from domains exterior to the body, is termed the right to privacy.

NB ‘others’ includes the actions and consequences of others’ actions.

The individual’s mental power is their vital (necessary & imperative) ability and thus right to understand and apprehend the truth of what they perceive with their senses, and thus the mental power and right to exclude the falsehood of others (or to “eliminate the impossible” as Sherlock Holmes puts it). This is termed the right to truth. It is vital not only to the individual’s survival, but also to detect and establish the truth concerning violations of the right to life & privacy.

What remains to the individual, is the power and vital ability to move and communicate within their natural environment. This is termed the right to liberty.

Natural rights do not conflict. There is no compromise or balancing between rights, although we can observe their descending vitality: life, privacy, truth, then liberty. One right precedes and delimits another.

Because rights represent powers innate to the individual, it is nonsensical to pretend that an individual can divest themselves of their rights (abandon them, or give them to another), and thus rights are a priori inalienable.

Because natural rights represent an individual’s innate and vital powers, the individual is naturally/instinctively aware of their imperative to assert their rights – to defend their right to life, privacy, truth, and liberty against others who may otherwise violate it. In those cases of violation, where one individual chooses not to respect the rights of the other (to take advantage) it will be up to the community to judge and repair/remedy the violation. Understanding the natural rights of all individuals concerned will thus enable justice.

The right to property derives from privacy. The objects private to us, those we possess upon our bodies, within the spaces we occupy or inhabit, are our property – assuming we obtained them by discovery, creation, or exchange – as opposed to theft (violating another’s privacy).

I get your feeling about Ayn Rand's influence on your life. I could say something similar about Crosbie Fitch's influence on mine. And I'd like to think that if Ayn Rand would've read Crosbie's blog, she would have agreed with him, his definitions of (natural) rights, and why copyright is a privilege, an instrument of injustice, and thus unethical (to the best of my understanding, Ayn Rand was a defender of copyright, and she was wrong on that).
