My assumption is that when this deflationary cycle transitions into hyperinflation, that "cash" will not be wanted by the debt collectors. FRN's will be revalued daily or hourly, making it unstable for use as currency.
Example-
If the mortgage company is owed $1,000 on the 1st of the month, and you mail them a check on the 25th, by the time they receive it and process it, $1,000 may only be worth $100. The same may be true if you pay in "cash" at the bank. You walk into the bank with $1,000 on the first and they say, "The value isn't there, so you owe us current value at $10,000".
My response would be to request that they take silver as payment. If they decline, I would choose to "miss this month's payment". It's likely that you wouldn't be the only one. It's extremely unlikely they could foreclose on EVERYONE. Somewhat like a reverse bank run. I'd imagine that "alternative" methods of payment would be accepted rather quickly. Especially considering you would be one of the few that has the means to pay at all.
That would be my primary reason for being "precious metals heavy" on investments.
