While I certainly agree that everything you've said about what an individual can do is true, I disagree that in the grand scheme of things that it will make any difference at global scale.

Telling people to change their lifestyle to fight climate change is the environmental equivalent of telling people to diet and exercise to lose weight. On one hand, it's obviously true, but on the other hand we have decades and decades of proof that requiring individual willpower to make societal-wide change is a failed proposition.

Large scale change is only possible with government and technological advancement, e.g. electric vehicle adoption is in some ways accelerating faster than expected, because as battery prices have come down, people have realized that electric vehicles are better in nearly every way. Better storage technologies are also making large-scale renewable energy sources more feasible.

So yes, it's a good idea to drive less and put solar panels on your roof, but let's not pretend that the requisite number of people will "follow your example" if it's too onerous for them to do so.

That all sounds accurate enough. I would say you won't get PV on everyone's roofs without some major subsidies and/or tax-breaks; or, I suppose, if natural gas prices increased enormously... But any or all of those could come about, without even a huge amount of political consensus, I would think. I was lucky enough to buy a new home that the builders had added solar to, so it was just part of the mortgage for me, but cost of retrofitting is still not negligible (even though the hardware is cheaper all the time, the labor isn't)

Renewables are already getting ready to climb the hockey stick of exponential deployment due to their cost, and EVs are not far behind. Better policy would of course speed the transition, but at this point at least, renewables are unstoppable. The faster the cost of power drops due to renewables, the more cost advantageous to electrify everything, further driving a fossil death spiral.
