There are lots of ways to index prices. Gold basis, silver basis, mixed bag of commodities, bitcoin basis (might be too new and volatile for that to be a good bet though), some-fixed-point-in-the-past fiat basis (e.g. USD of the year 2000), and so on. Hyperinflations are nothing new around the globe, and places that have experienced them have handled them okay, or at least muddled through.
There is no guarantee we will even see hyperinflation: it might just be very high like in 1975 or modern-day Argentina, but not hyper (which is total failure of the currency). However, von Mises's theories suggest a hyperinflation is very possible in our current financial climate. Only time will tell.
IMO, hyperinflation won't happen. It would have too much of an impact and it would probably not even occur.
Exactly, hyperinflation only happened when the productivity is very low and the demand for goods/services are very high, currently the productivity is insanely high thus the competition between producers are so tough that they must keep lowering the price
They have lots of ways to reduce the cost like outsourcing to other countries and automation. When all the cheap labor have been used up, there will be robots
On the other hand, since inflation do not happen, bankers print more and more money to put in their own pocket
Only in a war when large amount of goods were destroyed quickly, there will be a run away inflation
