You’re comparison misses an absolutely cirtical point: Many people here (and I concur!) understand that there is a very clear difference between money and currency. Money is the actual medium of exchange. Currency is its form. As far as I can recall (however, I haven’t taken the requisite time to be an authority on the subject), no currency has ever successfully circulated that does not directly represent a commodity money absent coerscion. If you can find one, I’d love to see it.
So, with this in mind, let’s look at your different alternatives again:
- Coinage: Contains money. A genuine coin always contains a consistent, well-known amount of the actual money commodity. Possession is sufficient to prove ownership of the base money.
- Backed Bank Notes: Represent claims to a consistent, well-known amount of the actual money commodotity. Redepmption required to prove ownership of the base money.
- Digital backed Bank Notes: Same as above for normal bank notes.
- Crypto-currency: Unbacked. Represents no actual money. Fiat. In order to even come close to the alternatives above, you must prove that crypto-currency represents an actual commodity, and I have seen no cogent argument that it is.
I’ve seen you make no argument that crypto-currencies would arise absent coerscion. The “advantages” of crypto-currencies are that they are effective black-market tools. I don’t see this as a convincing argument. Especially since the market participants by definition can simply eliminate the coerscive element behind currency instead of attempting to adopt a crypto-currency, and then the market will likely return to use money.
And if your goal is simply to create a black-market fiat currency in order to give governments the finger, you’re going to very quickly find yourself on the losing side of the euqation. Even if you obtained wide adoption (which I doubt, for reasons above), governments will push back, and no system that I can see will stop guys with guns and the ability to obtain resources with guns from asserting control when they deem it necessary. You seem to think that governments wouldn’t simply fine, confisacate, and/or jail merchants which accept crypto-currencies. Which prevents “wide adoption” very effectively.
Many technology purists believe that they can code around men with guns and the tacit authority to use them. But all you’re trying to do is avoid tackling the real problem, which is the coerscion itself. And I personally believe efforts to avoid this central issue is a fool’s errand.
