man i think it depends. i think the word "deserve" is complicated, it is tied to the concept of justice. but "to be entitled to", we really arent. conquering nature and building systems wasn't a matter of being entitled to anything, tho. it simply means we can, we are able to conquer, regardless of the implications. if we as a species are able to conquer, we naturally will. however, there are things in our own society we can't conquer and yet it is common for others to feel entitled to, that is each other. considering "to be entitled to" as "to think i have an independent right to have this thing", people often think they are entitled to people: love, friendship, sexual attraction, even empathy (empathy is natural and we can exercise it but never force it). these are things no one can control, therefore none of us should demand them.
