"Conclusion
If ‘natural’ implies ‘all’ or ‘common’ or is notmeaningful, perhaps the question should not be: “Are there any ‘natural’ rights which can be derived from reasoning?” but “Are there any rights which can be derived from reasoning?”
Most natural law theorists that I have read consider 'natural' to refer to certain common aspects evident in man's nature, such as rationality. It is obvious that all human beings can reason, more or less.
I suspect that the author of this article has not read the magisterial Natural Law And Natural Rights by John Finnis.

Finnis defines 'natural law' as "the set of principles of practical reasonablness in ordering human life and human community " p. 280
There are various approaches to reasoning out rights. One approach, pioneered by Hobbes, Locke, and Rousseau is to define rights in terms of a social contract. This is also what the contemporary philosopher John Rawls want to do:
“Rawls’ theory is based on a thought experiment in which people, separated by a ‘veil of ignorance’ from knowledge of their particular lot in life (wealth, social status, abilities,…) reflect upon the rules for social life that they would make in advance to bind themselves, whatever their position.” Brenda Almond in P. Singer A Companion to Ethics p.265
If the idea of ‘natural’ is not useful, then rights in the social contract are defined on egoistic, utilitarian, or theological grounds. A citizen will accept the social contract because it is good for him or her; or the greatest good for greatest number of people; or God’s way. Rights defined in strictly utilitarian terms are based on specific objectives and in this sense lack some of the authority of an idea of ‘natural’ rights. As a practical matter, this may leave utilitarian-based rights on shakier ground as the social objectives change. For example, in the US there is
currently a debate about the right to bear arms, a right that I believe may have been useful 200 years ago but not today.
Regarding the author's statement, "a right that I believe..." above, natural law thinkers do not consider the utility of a right to be its sole justification. Nor would they ever consider their belief (preference) to be relevant.
This article is very misleading on the idea of natural law. Read Finnis instead.
In the US Declaration of Independence, the Founding Fathers wrote:
“We hold these truths to be self-evident … that all are endowed by their creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness.”
As self-evident, these truths did not have to be defined by reason. Analogous to geometry, where axioms cannot be proved, rights are taken as social axioms.4 In these arguments, rights are not proven, but provide the basis for generating proofs of political and moral theories.
But of course this still leaves us with the question of how self-evident any rights really are."
