The need to over-provision a grid is obvious, but…
> 10x overprovisioning here looks a lot more expensive.
First: Why do that by a factor of x10? Best redundancy here is geographical diversity rather than a fatter… I was going to say "cable", but it is (or collectively, they are) the order of a few square meters cross section and that feels wrong as a name. But that thing is best spread out, not kept singular and made wider, whatever you call it.
Second: Even x10, the main limit is "that's a lot of stuff to mine, how do we reorganise the miners from coal and oil to metals" rather than the $ cost — while "a trillion" of anything is a lot for one person to contemplate, compared to the cost of what is currently dug up and then set on fire to provide the same power, it's quite cheap.
