Money.

Now that USB-C is the required cable, people can go out and buy any cheap cable they want. The law turned a proprietary cash cow into a low return commodity item.

Don’t need to, just down-blend from the available fuel used from weapons put out of commission as a result of disarmament treaties.

Now, about those materials used to construct solar panels…

Raw material is usually a small fraction of the cost of refueling. I would also argue that the Russian-Ukrainian conflict is a small blip in the lifetime of a reactor, ~80 years. Transient pricing will have a negligible effect on the LCOE.

This is false. Nuclear has a very competitive levelized cost of energy (LCOE). Nuclear has high upfront costs but fuel is cheap and the reactor can last much longer than solar panels. The big picture matters not just upfront costs.
