To my benefit, I did change the meaning of the word to be:

Note: The term unsustainable used in this post's context, is to also mean "unpopular, and/or not fully adopted, not chosen, or not accepted by the mainstream population."

We need certain fundamentals that will be adopted or chosen by the mainstream population just to have a functional and sustainable environment, so the majority doesn't war and feel displaced. (History teach us that overthrowing and war, is the inevitable conclusion during turmoil of competing societies and countries).

But I like the idea of the "aim" you propose. :)
