Gold. Is it any use?

[TOF]

I think the main point is being missed. It's not so much about how much PM's are worth now, or how much they will be worth post TU. Throughout history to way before Saxon times precious metals have an intrinsic value of some form or another. It doesn't matter whether they are worth £1,000 a 1,000 loaves of bread or 1,000 worms. The point is, gold and silver have always been held in high regard.
Don't for one minute think everyone will be in the same boat after armageddon. The rich and powerful will still be there and they WILL be happy to fill their purses.
It never ceases to amaze me how it's always the common man who survives. If the place were to go to custard on a permanent basis, the Wolves of this world will soon have a good old feudal system going, and that's when you need your PM's. Get in with the big boys and buy a Wolf.
