I really have no idea, but your question suggests its own answer: fiat currencies are also designed for eternal inflation (I think you swapped inflation with deflation) and many people consider that a boon.
When too much fiat is printed, it decreases its value and is called inflation.
But when assets lose value, it is called deflation.
So, do you call cryptocurrency a fiat currency or a speculative asset? Because falling value will happen, it will be just termed inflation or deflation.
