I'm all for splitting up the big banks into more narrowly focused units.
Yes, the current system has to be reformed and banks must go back to basics and serving the economy, not exploiting it recklessly. Hope they manage to do this without debtors collapsing, the whole system works as long as you find additional people/companies/govts. to take over additional debt. Hard to put it in words for me, but because of the interest and compounded interest the system works as long as the economy is sound enough to be able to increase debt all the time.
Re Precious Metals: Take a look at this Chart, it shows how much ounces of Gold you need to buy the Dow, the Dow/Gold-Ratio. In times when the economy was bad (1930ies and 1970ies) Gold performed much better than stocks (and anything paper or trust based).
In 1999 for example you needed almost 40 ounces to buy the stocks of the Dow, when the economy was totally down it went down to almost 1 ounce per Dow. We have a bullmarket for years now, so you certainly can't call it cheap anymore. I'm hoping for a correction which should go below 1000, maybe even below 800, Silver under 10$ is possible, too IMO.
Plus Gold and Silver have been highly valued in almost any society (except isolated tribes etc) in history. A piece of gold is perceived something real, as far as I know there is not a single example where paper money didn't collapse to zero sooner or later (the oldest currency so far is the Dollar I think).
But you are right, it's a good idea to focus on things you can really use in a crisis. That book would be very interesting, can you find out what the title was maybe?
To have something to trade and store value in a crisis, maybe raw coffee beans would be one egg to put in your basket (uh, poor english;-). I heard unroasted coffee beans can be kept for decades if you store it savely. If the crisis gets bad, there is still many people who are desperate for a coffee (in WWII coffee and cigarettes was very good to trade over here). Or sugar to distill your own booze for trading, sugar can be kept for decades, too.
Best regards, hope I am wrong, because this looks scary:
(optimistic interpretation: US govt. is just trying to offset the drop in non-military durable goods with something else)
