Do you suggest we keep savings in cash and physical bonds, stock certificates and gold ingots under the mattress?

I pay cash often but even so I very rarely have more than $1000 in cash at any given time.

Which is smart because at least in the US there's a large portion of the country where police can use civil forfeiture to take your money, even if you are not guilty of any crime.

Not necessarily under the mattress but it is smart to diversify your liquid assets location

I do all my day to day in-person payments in cash, yet all my assets would be just as vulnerable to that kind of attack as those of a completely cashless person.

Look, I really despise the government too, but...

... FDR confiscated the gold lol. If they want something of yours, they will take it.

When cash was used for most retail transactions, you were still going to have a couple thousand on hand at most. That won’t last long. It’s the payroll side, not the POS side, where that matters.
