"For economists, a natural measure of freedom concerns the range of things one can do. The greater one's "opportunity set," the freer one is to act. Someone on the verge of starvation – doing what they must just to survive – effectively has no freedom. Viewed this way, an important dimension of freedom is the ability to realise one's potential."

Actually, the above is not for economists only.

"As Berlin showed, negative and positive liberty are not merely two distinct kinds of liberty; they can be seen as rival, incompatible interpretations of a single political ideal. Since few people claim to be against liberty, the way this term is interpreted and defined can have important political implications. Political liberalism tends to presuppose a negative definition of liberty: liberals generally claim that if one favors individual liberty one should place strong limitations on the activities of the state. Critics of liberalism often contest this implication by contesting the negative definition of liberty: they argue that the pursuit of liberty understood as self-realization or as self-determination (whether of the individual or of the collectivity) can require state intervention of a kind not normally allowed by liberals." https://plato.stanford.edu/entries/liberty-positive-negative/

As I posted before, rather than human rights and freedom, the emphasis should be on human ability in general and human capability under specific situation.
