Agreed! But my base assumption is that suppliers are generally better-equipped than consumers to absorb sudden, unexpected costs.

But I also feel this is all extraneous to the larger point, which is that we can set up a fiat-based finance system in whatever way we feel, just like we could develop a blockchain-based system that allows transactions to be reversed under certain conditions. I'd like to use the one which releases an order of magnitude less carbon.
