Couple points: first, hyperinflation is not a myth. It has happened (germany in 1920s, zimbabwe couple a years ago, argentina now and 90s?...) and will happen again. The root causes are printing too much money, easy credit (which leads to a bubble), and then a deflationary collapse (return to sanity) which the printers try to alleviate by printing more. This is like putting a bandaid on cancer, it hides it but it just keeps spreading and manifests itself elsewhere.
The way a gold standard, or any kind of peg where the govt has to exchange a commodity of a finite amount which they cannot reproduce (hmm, wonder what would happen if we had an oil standard), is that it limits the printing that can be done. That is why the US govt took all the gold from US citizens and made it a crime to own gold; it could not redeem the demands. If people came with $20 and said give me the gold, I do not trust that you are not printing and devaluing the dollar, the govt would run out of gold too fast. So in 1933 Roosevelt took away the gold and made the money purely fiat (for US citizens). In the 1970s the same thing happened again. Foreigners were demanding gold because inflation (paper being printed) was eating away at their purchasing power, the US was loosing gold like crazy (to make up for the dollars being printed) so Nixon said no more, you have paper and you are not getting our gold. The amazing thing is that people accepted that, and still continue to take paper that has been printed more and more. When you study money creation, how it is created, it is really amazing. I am not judging whether right or wrong, or what should be better, but it makes my head hurt when I look at it and think I understand it because it does not make sense... But anyways, a gold standard, where paper can be exchanged for gold, puts a limit on printing, or inflation. If the value of the dollar starts to go down to quickly, people will exchange them for gold to preserve their savings / wealth. The govt will start running out of gold, and have to start changing their monetary policy. We do not have any such brakes in today's climate, printing is feasible and is happening.
I have gold and silver, as stated previously. I bought most of it several years ago, when I was convinced of where we are heading. I will still buy gold and silver as I get more wealth to protect. I see it as a hedge against the printing, if printing increases, money goes down, but gold goes up. And if there is hyperinflation someday, then I am ready to buy some cheap real estate (in gold term; in dollar terms it will be crazy expensive). So a hedge, and insurance.
Bubbles are interesting items. I remember the run up to the tech bubble; people were saying buy, buy anything, it is crazy but they are all going up. I looked, no earnings, no business, no business plan even for some, looked too crazy, I did not even know how to buy a stock back then, too busy doing other stuff, I stayed out.
Then the real estate bubble, same thing. People were buying like crazy, easy to get loans, people quiting their jobs to "get rich", same thing, a bubble was not possible until it was already half way down, even then many (see choice speeches from Bernanke, Geitner, Greenspan, etc) denied it. Remember that it is easier for most to believe the easy lie than to face the hard truth...
So bubbles and money and history, they are kind of a hobby of mine. Not so interested in memorizing dates, etc, but interested in why things happen, why people do the same things again and again, why money systems inevitably lead to inflation (no control over printing) in the end, etc. So understanding human nature, and what has always happened, I feel confident that similar things will happen again and prepare accordingly.
I agree with Matty that there is a ton of pessimism in goldbug communities, but it is worth reading the counter to the koolaid given in the media just to stretch your mind and make you think.
And yes, Bryan, I totally agree that saving your wealth in dollars is not good in todays environment, govt inflationary policies are going to steal it. They want you to spend, to keep the economy limping along, inflation is a means of making you do that (we should buy before prices go up, if we save we just loose anyways, etc...).
And I also agree if you do not know anything about this stuff, if you do not understand yourself why you should buy gold or silver than you should not buy based on someone's recommendation. But I highly recommend learning. Some good references above, get both sides of the argument. Maybe you will arrive at the point I am; not sure which will come first, but wanting to be prepared for whatever comes...
