Good ideas here. I will only address a few of them. Here goes:
RE: I don't get the point of this. You can't get paid or pay employees in metal coins.
Recent case in Los Vegas got aquital or hung jury on all counts of an employeer paying his employees with gold American Eagles (that under US Law are Legal Tender stamped at 50 bucks for the one ounce coins). IRS was pissed because this guy recorded the pay at 50 bucks for each coin when each coin brought 500 to 1000 bucks in the open market. This allowed the employees to avoid having to file income taxes returns because their pay did not exceed the minimum amount required (somewhere around 7000 bucks of income).
RE: Also you have to pay capital gains when you sell gold coins for a profit. That makes them horrible as investments from every conceivable standpoint.
Only if you convert them to federal reserve notes. You can use the coins in barter and pay no tax. And, if you're really into record keeping, record the transaction as the amount of dollars stamped on the coin.
RE: I think it's pretty safe to predict that a government will still exist even if the currency collapses, and that they will issue a new currency that will most likely not be based on any commodity.
I think it's a pretty safe bet that if the government looses it's ability to have it's currency accepted, it collapses and the market creates the new standard of "what is money?"
RE: The transition to the stateless society is philosophical, not material.
Just my opinon, but I think the transition to a stateless society is inevitable not philosophical.
RE: I don't even think that a free market currency company would use commodities as a backing. Commodities are so... volatile in terms of price, and not to mention heavy. I think an electronic currency is much more likely.
I disagree with the first part here, but your electronic currency solution, with some organization that has great trust, auditing and transparency, is probably the way to go. A great example of how this might work (OK a state government was the issuer here) was in the book Molan Labe.
