You still don't seem to be understanding what I'm writing. (I don't care if you agree, but it would be nice if your response seemed like you understood.)
It's not that someone is looking at an NFT business with a solar farm and thinking to themselves, "maybe I should get me some of those fancy panel things". If a big industry (and in the case of crypto, I'm using the term industry very loosely) with a lot of money were to inject that money into renewables, that would boost the renewables industry, likely lowering prices in the long term. Those lower prices are what would make the average consumer more likely to adopt renewables. And if you can keep that process going, growth and costs can keep improving (at least until market saturation is reached, but market saturation of renewables would be a very good thing).
This isn't based on speculation either. We've already seen this work with government subsidies and incentives for the renewables industry. It's just that we've reached a point where those subsidies aren't enough to keep the process going at a good pace.
In the long term, renewables can be very cost effective. And there is some evidence that crypto may give the renewables market a significant boost. Whether that actually WILL happen is admittedly pure speculation at this point, but it is within the realm of possibility. Even partial adoption of renewables by crypto would not only help mitigate the absurd energy requirements thereof, but also help fuel growth in the renewables industry.
That's not to say that crypto is saving the world. It's not. It's a thing, with flaws, and hopefully someone will design a better thing sooner than not, that isn't so flawed. But, if we're lucky, it might just incentivize the people who have the means to invest in something that just might save the world, largely out of their own self interest.
