I'm a pleb through and though but my thoughts seem to be aligned with yours. I can't imagine a world that @petertodd does where we will have to incentivize miners with a seemingly insane notion when it seems apparent that nations, like you said, will mine for themselves profit be damned. I respect peter a ton and I love to read his work but I have yet been able to budge from a hard disagreement when it comes to tail emissions.
