Even as someone with a position in both PM's and Bitcoin, I don't wish to see such an event.
Unpleasant things happen. One might argue if they didn't what would you compare the pleasant things to?
Life would be so difficult, complex, and miserable that it would not be worth it.
You could say that about the current state of things, especially in places like Argentina (50% annual inflation) or Venezuela (food rationing). As for the complex part I disagree. That might be the case with having to barter PMs, because they are cumbersome to actual transactions, but Bitcoin solves that. As for the miserable part, again, thanks to Bitcoin I feel a speedy recovery is quite possible.
My attitude is self centered around my own experience to be sure. I should have made that even more clear. But just as things could be worse in my relatively cozy situation (as a middle-class USian) things could probably be worse for those who are less fortunate as well. 'Ideally' from the standpoint of most of humanity, there would be a more equitable distribution and I personally would be much worse off than I am now.
As for Bitcoin being some method of readily solving the problems, I just don't see it. It would probably work out exactly the opposite in fact. Since I first became involved in Bitcoin, the main advantage I saw was that with some coordination, 'the masses' might be able to cause it to fail...because they are not going to have the ability to shake it out of the pockets of those who hold it. There might be some potential for holders to recognize this an limit their abuse, but that's pretty pie-in-the-sky. Humans don't tend to work that way. Thus, the chief 'advantage' of Bitcoin over gold is that the masses have no theoretical ability to cause gold to fail from a system's perspective. With distributed crypto-currencies they could simple prefer 'Massescoin' and start to value it among themselves. Theoretically.
I'd prefer to see things grind along as we see today.
Things only appear to grind slowly away at the surface. The macro state of events is much different and clearly unsustainable. The grinding has already ground along to the end of its tether.
The trouble is that that has been a pretty strong argument for the past 40 or 50 years. It's probably true, but fairly useless for most semi-precision planning purposes. When messing with things like Bitcoin and PM's which are relatively volatile it is quite possible to get into a situation where one is forced to sell at importunate times.
