There is an issue with that approach.

When they say free speech is a right, life is a right, freedom of conscience is a right and so on, they mean that others can't take away from you what's already yours. Our world, eh, is still that bad that this requires clarification and most people disagree with some or all of these.

I'd say in the situation where there are no white spots on the map, and growing food requires land and other such resources, and those have already been shared, - yes, these are rights. But a different kind by different logic.

A bit like the first part is reactive, while the second part is active. I'm bad with words.
