That's the central bank narrative, whether its a good thing or not I think is still up for debate. Regardless, this can still be done with crypto (in fact, Ethereum is inflationary and not fixed cap like Bitcoin is), except that speculation and capital inflow still drastically outpace the inflation. Presumably one day an equilibrium will be reached.
Whether a certain amount of inflation is good or not, is definitely not up for debate. Nobody wants something that is a medium for value to become so valuable that you can't use it for its original purpose.
Depends. Some gold seller used to advertise that in 1400 AD an ounce of gold would buy two good suits, and today it will buy about two good suits.
