Yeah, I want the assets I hold to increase in value, too, or at least not decrease.

Suppose you have some control over currency. You run a country. I'm that case, so you still want the currency to gain value compared to the alternatives?

Your choice is basically: holding currency is more profitable than building a house or running a business (or lending to those who do), or else less profitable. If you run a country, do you want houses and jobs and all that kind of thing, or do you want people to do better if they choose to hoard currency?
