Beauty as a rule of thumb of sustainability

I believe that somewhere in the core all things designed to be beautiful are also mostly sustainable.
There are many reasons to make that assumption.
When someone is designing or creating something, either it is a chair, a song, or a deed which is beautiful, means that there is an extraordinary amount of time and effort put into that, even if not directly then getting ready before that action of thing itself. It´s been done with lots of thought process, rethinking, refiguring, resizing, any for on analyse and aim for a highest possible solution. And if one has put such an amount of energy into something, or has been cultivating that type of state, they will want to make it long-lasting, therefore sustain, to be used, to wanted to be heard, to remember it for as long as possible.
Secondly, people tend to take care of , honor things that are beautiful...
