'Natural Rights' is a flawed concept.
(unless you believe in a god that designed life in a specific way, or other such belief)
'Rights', whether 'Legal Rights' or (the flawed concept of) 'Natural
Rights', are notions of:
Fair / just entitlement to some things.
Fair / just protection from some things.
Following are based on values (and some principles we adopt based
on values and the below) (to varying extents):
Justness / Fairness / Rightness / Wrongness / Goodness /
Badness / Moral / Immoral / Obligations / Duty / Responsibility.
Things (including living beings) have objective inherent qualities.
The value that one associates with an objective quality is subjective
and can vary from person to person.
Variances in value for the same underlying objective qualities
can arise from:
Different brain chemistries (including emotions).
Different conditioning (upbringing, environment, life
experience, etcetera).
Differing information (we can seek to inform each other)
Erroneous beliefs / thinking / logic / facts (we can seek to help
each other make corrections).
Varying values for natural (inherent) qualities can lead to varying
subjective convictions of goodness / badness / rightness /
wrongness / justness / fairness / morality / immorality /
acceptability / unacceptability / merit / demerit.
Subjective variances as to what entitlements or protections any entity
merits, implies that 'natural (inherent) rights' is a flawed concept.
