There are plenty of communities where they'll take precious metals at least. Coin collectors, for example. Plenty of ordinary "for sale" listings say "I'll take USD50 or two ounces of fine silver coins/bars." I suspect there's also a similar sub-economy in the apocalypse-enthusiast fandom where they're always predicting the death of fiat currency Soon (tm). Compared to bitcoin, I'd actually argue the fiat on/offramps are easier-- most any local coin dealer or pawn shop will trade a Gold Eagle, Maple Leaf, or Krugerrand within a few percent of spot price and with immediate turnaround, and it's got plenty of well-established legal and tax frameworks around it. Actually, that brings up an interesting question: do we know how to insure cryptocurrency yet? If my house burns down, and my physical wallet goes with it, they'll replace a nontrivial amount of paper currency that was destroyed-- something like $500. But if the fire took out a flashdrive with the key to a BTC wallet worth $500 in it, would their responsibility be to replacing the $500 in lost value, or "here's a new 16Gb flashdrive worth $4?"
