I have heard that for a while and I always assumed that Bitcoiners eventually will not accept worthless fiat. But I never conjectured the problem is that the fiat price is an unknown .... massive tracking error, even before any heavy debasement goes on. Maybe good tracking in $USD for instance but wrongly tracked in another currency. This situation will by marked by sharp , spiked corrections and then more tracking error. Maybe Bitcoin will have to be tracked in Crude Oil Futures .... something backed by tons of trade where people bicker over the price. Then agin, you'll have the COMEX price , the OPEC price and the black market price or from something like HODLHODL, a non-KYC exchange.
