This really isn't true. Most people aren't even close to reckoning with what net zero would involve. Most people haven't even got a stock vs flow model of carbon and think that lowering co2 emissions means reducing global warming. (As opposed to reducing the speed of the increase).

You yourself haven't got a model. If we stop using fossil fuels today, billions die. The energy from fossil fuels has generated widespread benefit and allows our current wealth. And also heats the atmosphere.

The emissions of the bottom 90% globally, and the emissions in the products they use are more than enough to sustain global warming.

Fobbing the problem onto "the other", however you define them, is another way to justify doing nothing.
