This is a very earnest piece and you are making a valid point. But, your conclusion is invalid.

Your argument is that after a certain point in the industrialization cycle greater levels of output become possible at lower levels of energy inputs and result in lower levels of pollution.

That part of your argument is true.

You then carry that trend, which is actually based on ever improving technology, to a "utopian future". One where, logically we should be able to "grow our way to Net Zero without having to sacrifice anything".

"a future with wealth and without climate change will come into sight".

Unfortunately, reality doesn't exactly work like that.

The ONLY way this works is with UNLIMITED CLEAN energy. You have to have that for your scenario to work.

Unless CHEAP, EASY, FUSION power happens very soon we will not be able to 'grow" our way into the paradise you imagine.
