Here's one thing the US can do about: take nuclear power seriously.
Also better for international relations. Control the advancement through US capitalist compan's patents. Distribute tech through deals and subsidies with other allied, like-minded, nations. Secure energy sources (Sprott). Reduce dependence on fossil fuels in allied nations (like Europe and Japan's craving for Russian fossil fuels). Plan A is grow cities and grow wealth through cheaper access to more energy--Use Bitcoin mining as backup for extra power where new micro-nuclear technologies are being tried out as a plan B. Bam, soft power.
This is probably the biggest problem bitcoin will have with institutional investment. Funds are increasingly viewing and evaluating investments in the lens of ESG and it will be hard for them to rationalize including an asset in their portfolios that increasingly pollutes, or by association a publicly-listed companies that put a lot of BTC on their balance sheets. I'm curious how this problem will be tackled especially as network difficulty increases. Not confident the community would want PoS.
This will matter until it doesn't.
It's clearly disingenuous to promote the idea that btc is a massive polluter, when the money they hold pollutes more to keep it moving.
But unfortunately, it's not so clear to most people, that their incentives prevent them from seeing past their own fiat bellybutton.
