I wouldn't look forward to it.
Total economic collapse means no jobs, no shipping, no stores, no hospitals, no police protection, no government, no utilities (gas, electric, water, waste services)...

After all, who would show up for work as a doctor, nurse, policeman, state or federal employee, etc... when you aren't being paid in useful currency?

When all of those things go bye bye, the next thing that falls is Private Property. You only own your house, cars, boat, RV or other possessions because you can physically enforce your ownership.
