Not sure about your logic here. The more exposure you have to an inflating/hyperfinflating currency, the more risk you carry. Your house holds value, but the rent in fiat you collect doesn't. Every month you collect X liras, but they become worth less and less. You're assuming you can reprice rent on demand, but contractually this is dependent on the locale.
> In a stable environment, using currency as store of value for anything more than 3 months is stupid
You only seem to be thinking in the single dimension of currency for the average person. You forget that all government treasury bonds (pretty big and important financial instrument in any economy) are denominated in some fiat currency. 10, 20, 30 year bonds. There are macro affects when people no longer expect or trust a currency to hold value. It is part of how debt crises occur.
> If you really really really want a currency that acts as a store of value, of course there is the King Dollar, the greatest currency in the history of currencies.
People think Bitcoin is a monetary experiment. But it really is the modern day fiat currencies that is the huge experiment.
