You're some saying it'll be different this time, and the only explanation you give is, 'communications' and 'electronic', and yet plenty of fiat currencies have collapses under such systems. Again, every fiat currency that has ever existed has collapsed, sure there are some new ones that haven't yet but to believe they won't is magical thinking.

Again gold, after thousands of years, is still being hoarded in vaults by every major and minor world power, you really need to review some history.
