I understand everything you say but don't agree with a lot of it and certainly don't care for you patronizing remark. Most fiat currencies today have nothing to back them, except the word of increasingly untrustworthy governments. The US has been fortunate to have the Dollar as the world reserve currency for 70 years but that seems to be about to change soon.
The link between paper currencies and gold could be adjusted to fit with the gold reserves available, that could back them at a practical, and not necessarily fixed, level. I see something like that as better than nothing.
Of course I disagree about the gold price suppression - there are several big banks that have interests in keeping the price down and at the moment they are able to mostly control the price. However, I so think that your "free-floating" phase may be just around the corner. Gold is real money so I do have an interest in it.
