Earth's resources are finite, both in terms of raw materials and ability to absorb pollution. Stewardship of our resources entails the regulation of the things we create with those resources such that our collective consumption is conserved. Such oversight is both prudent, and as history and global outcomes teach, quite necessary.
I don't disagree with your statement, but an increase in design durability also does those things. A phone that you can drop and it doesn't break creates less pollution than a phone that you can drop and replace the screen.
