Fair enough.
I may have confused you with another poster, who also mocked "dystopian fantasies" about the power grid going down. Which IMHO is a very-real danger, and one of the first things to fail when the system starts collapsing.
It's not important enough for me to spend time on. I said on another post, we all prepare for what we sense might happen. Some move; some buy Hummers with crawl treads; and some stockpile shelf-stable food.
You pays yer money and takes yer choice; but I would not put money into electronic scrip that won't have any use once the Worldwide Web is down.
