We say: I need it. Do we not mean: I want it? We find some things necessary, Others desirable.
Humans, I find, lack the disposition to distinguish between the two. We lack the desperation to say that we truly need something.
Only desperate humans truly need things. You see, humans have created so many shortcuts in nature that it is entirely unnecessary to depend on any one material.
However, we have large, far-seeing eyes that fixate on particular subjects. Our minds fixate on this subject at the same interval, and we are left with desire that will never be relinquished, For if it is satiated, we come back for more.
