God is love. God is just. God is merciful.

[John V]

No, they don't. The denial of a need being met is not evidence regarding anything about its nature.

Yes, it is. Air, water and food are fundamental human needs because humans can't live without them. Things which we don't need to survive are not fundamental human needs.

Why would I have to prove anything of the sort?

Because you said, "the fundamental rights derive their legitimacy from these needs which is why they are objective."

Just because you have a need - fundamental or otherwise - doesn't mean you are entitled to having those needs met.

Then why do you say that fundamental rights derive their legitimacy from fundamental needs?
