When your just store your Money in gold, bitcoin or under your bed, you are effectively taking out all that power to actively create wealth from the economy, and you are actually producing an economic slowdown. You just become an economic parasite that not only do not contribute to economy, but benefit from the work, intelligence and the willingness to take risk of all the others that are making your country grow and be a better place to live, while doing nothing.
You can tell central banks: You are just a money printer that not only do not contribute to economy, but benefit from the work, intelligence and the willingness to take risk of all the others that are making your country grow and be a better place to live, while doing nothing

Controlled and not artificially manipulated inflation is a socially good think, because it damages the hoarders that don't produce nothing, and obliges them to lend, invest or use their money if they don't want to see it slowly disappear. Deflation is socially bad because it produces just the opposite.
Inflation is slavery, you will never feel safe even you have made enough saving to spend the rest of your life, since your saving are eaten by inflation year by year. In such an environment you have to continously work/invest like a slave. From when did people lose the freedom of retire with a decent amount of saving?
