You know, it's a bit hard for me to understand how every household buying hundreds of kilograms of hard to mine metals is somehow a solution to the energy intensity of modern civilization. But maybe I'm just very nearsighted and it'll work.

Well, by that logic, I have some great sophistication going on in my household..

Several devices that took EUV machines(that cost hundreds of millions each) to etch login onto themselves - microchips on my laptop, phone etc.

A pipe constantly supplying flammable gas that was probably mined thousands of kilometers away just so that I can burn it and heat up my water for shower.

A very dangerous to the environment - refrigerant in both my fridge and heat pump.

A tank full of dinosaur juice in my car, which itself was machined and built with some exotic metals mined somewhere else in the world.

What difference is a few more kilograms of futuristic substance that can save energy for my house make?

I know hundreds or thousands of kilograms of LFP batteries in my backyard in feasible today. But who knows. Maybe we will find a way to mine Lithium or replace it with Sodium and the whole process would become “normal” like the metals in my 3 ton car.

You summed it up pretty well. I struggle to understand the idea that increasing consumption will lessen the impact of previous consumption. If this is our only approach, extrapolation says we're doomed.
