I don't disagree with you, but this is why nothing will happen and everyone has been planning for a 2-2.5C breach by 2050.
China, India, Vietnam, Indonesia. Brazil, Nigeria, and others are continuing to build out capacity. While this capacity is much more green than past buildouts, it's still in aggregate going to have a significant downstream impact on overall GHG emissions.
It doesn't matter who deploys more renewables or less when countries like China, India, and others continue to expand coal and ONG at reduced but still significant rates.
But they can morally push back and say North America, Europe and Japan industrialized via similar externalities.
And the reality is countries don't care. This is why China is now export controlling solar technology and IP [0] at the expense of India and other large members of the global south.
The reality is most countries are going to rush as much capacity as they can until the externalities can no longer be ignored en masse (probably by 2040-45).

Is existing solar tech insufficient?
