We are how the world is built and what is produced.

Look - I'll offer an olive branch here: You're right that POU is a tiny fraction of our total environmental footprint as a species (10-15% gets mentioned often). You'd be absolutely correct in saying that taking shorter showers is a drop in the bucket vs almond farming in the frickin' desert.

But all that overhead, from mining to manufacturing to shipping to that god-awful clamshell packaging (also made of oil)... Is still only because we demanded that iPhone, those almonds, that Hummer.

Not a single gigaton of supply-side emissions are because the evil manufacturing industry "wants" to make iPhones. They want to make money, and for our part, we can't throw it at them fast enough regardless of how awful their products are for the environment.
