Your five AI excuses may hold some water, but the bucket does have badly leaking holes.
I wasn't around when petroleum became a viable energy source, but considering it exceeds the length of time it has been around compared to green, they are mostly that; excuses. When petroleum began to be a viable energy source [1890s], the infrastructure already had electrical power available in big cities for ten years, and the two grew in availability together. What's green's excuse? Well, one that isn't mentioned, because it tries to be a major selling point, is renewability. Being intermittent, it isn't that, at all, is it? It should be very naturally compatible with current infrastructure. But, currently, it's really not all that naturally renewable, is it?
Virtually every technology has high up-front costs; it certainly is not exclusive to green. Television, for example, and who does not have one, even if "poor?" Cell and smartphones, personal computing...
Energy storage is another misfit excuse. Maybe green should not have been politically selling the eradication of fossil fuel, as Biden promised, when green is no where near to replacing petroluem, and not maybe for another 50 years, minimum, according to its progress to date.
As I said, ya'll need AlGoreGooeyJuice, but that is as vacant an idea as a current typical Democrat head.
Political/Regulatory Barriers: oh, boo-hoo. If green was technically capable now, and truly competitive with petrol, there would be no political strife suffered by green, ergo, no regulation issues, either. Yes, you are fighting an image issue, but that's not petroleum's fault. See above relative to tech/know-how issues.
Economy-of-scale/public awareness: What scale and what awareness? Green lags petrol by a mere 30 years, and petrol really did not get its infusion of strength as a big-league energy source until after WWII in the late 1940s; almost 50 yeas after inception. Awareness is hurt by green's own salesmanship. It has been so badly sold, as a miracle energy, it's a total flop. Green is washed up. and may not survive it's own sales pitch.
