[American Constitutionalist]

The network of Global trade will be non-existent ?

Local communities would have to trade with locally produced commodities like grain, corn, food, coal and barter ?

For example a farmer has silos of grain that they can use to barter with those who would mill those grains and give a portion of that grain to those who mill it for them.
A farmer can also barter grain, corn for gasoline to keep running their farm equipment.

The non-producers would be forced to starve and then go extinct ?

A farmer bartering a silo of grain?

Cumbersome.

If he needed only gas for his tractor...he'd exchange only a few wheelbarrows of grain for a few gallons of gas. Oh, but the gas isn't available from his neighbor, it has to be piped in from half a continent away.

Same for each little item the farmer needs. So...what would the farmer's reaction be in such a downturned economy? I mean, he wouldn't--as a practical matter--even bother to produce that silo full of grain.

No. The farmer would cut production down to a level to what his own family and neighbors could immediately use, or use for immediate, local area barter. Rememeber, in a broken economy there are no trains accepting money or credit to haul a silo of grain to the regional exchange.

I.e., we all starve in the cities and suburbs.

Scary, eh?

[Farmer Dean]

Bartering grain for fuel is one thing,but what do I do when I need a new concave or rasp bars for my combine.Or new drive tires for my big John Deere tractor?
Besides,the government will come and steal all my stored grain in an emergency.
