From what I know, it's likely that it's true, but political will doesn't want to do it - partly because of entrenched interests, partly because there is a limited amount of short-term pain, and partly because some people are just arseholes who have some combination of 1. think it can be wished away, 2. just plain don't believe it or 3. simply don't care as long as they benefit.
Yes, exactly this.
But my frustrations at it all won't let me put it so calmly and reasonably as that, so I thank Dio for rephrasing it for me.
I guess the example here is Australia:

‘Go hard and go big’: How Australia got solar panels onto one in every three houses
[...]
For a brief period over several weekends this spring, the state of South Australia, which has a population of 1.8 million, did something no other place of a similar size can claim: generate enough energy from solar panels on the roofs of houses to meet virtually all its electricity needs.
This is a new phenomenon, but it has been coming for a while – since solar photovoltaic cells started to be installed at a rapid pace across Australia in the early 2010s. Roughly one in three Australian households, more than 3.6m homes, now generate electricity domestically. In South Australia, the most advanced state for rooftop solar, the proportion is nearly 50%.
So, you know, you ask whether it can be scaled up.
Oz has scaled it up to 3.6 million homes - 1 in 3 of all Aussie homes, and 1 in 2 if you're in South Australia.
That one wasn't even political will. Indeed, most of the growth occurred under their previous pro-coal Liberal government (for clarification, Australian "Liberal Party" is equivalent to UK Tories and American Republicans) who absolutely were not encouraging it whatsoever. It was very much "grass roots" - which is why, when I talk about that, I don't think it's infeasible. Because Oz already did it - or, at least, a third of the way there in about 10 years.
China is also way out ahead. They have a third of the world's total solar capacity. It was around 250GW in 2020 - which, for context, is equivalent to 80 Hinkley Point C nuclear power stations. And, yeah, imagine how much and how long it would take to commission and build 80 Hinkley Point nuclear power stations. China's already done that 4 years ago and has been accelerating ahead.
Another one to keep your eye on, in light of recent news about the steelworks in Wales, is that Sweden actually did front up 3 billion euros to invest in a hydrogen-powered blast furnace that feeds an electric arc furnace, so that they can produce carbon-free virgin steel (the trade union plan that the UK government and Tata Steel rejected in the UK). So, as I say, keep your eye on that one and compare its future fortunes to the steelworks in Port Talbot. Let's see who made the right decision. My money's squarely on Sweden.
Heck, even within the UK itself, there's amazing stuff going on up in the Orkneys, who're already more than 100% renewably powered. In fact, they produce too much and it's causing headaches for them in how to deal with the excess:
So, the contention that it could happen if the will was there is not faith, you understand - hey, I'm an atheist and I don't do faith - but it is an extrapolation of these (currently too isolated) examples of where it's already going down. And, like, some of these are already impressive scale, such as 3.6 million homes and rising in Oz, so they are scaling up, seemingly quite easily, as there's not been any talk, thus far, of shortages or anything in that success story.
And the thing with renewables is that they pay for themselves. Short term initial costs, yes. But, in the long term, they pay for themselves in savings and selling excess generation, and so you actually, in the long term view, paid nothing for them. They're free, in "total cost of ownership" terms. In the even longer term, they'll keep making savings and selling the excess beyond their "pay back period", so you could even say that, in terms of the complete life cycle, they actually have a negative price.
So I would agree with you, if you're suggesting that governments should get involved to provide subsidies, incentives, interest-free "loans" and stuff to get the ball rolling, to overcome the hump of people being able to afford to install.
But, like, due to the "negative price in the long term", there is the notion that the same calculation works for governments too, in a "wider economy" way. They spend taxpayer money to help people install. But then those households have reduced energy costs. More money in their pockets to spend domestically. Less leaning on the benefits system. It can also work at that scale too - that if the government forked out on insulation and renewables for folks, it would boost the economy and keep it boosted, feeding back into tax receipts. It's more indirect, but the same basic idea holds that, in the long term, the taxpayer ends up paying nothing for it and then goes into profit thereafter.
