But it leaped out to me you missed, probably on purpose, portability and divisibility from your bullet points.
Divisibility:Why bother discussing divisibility? It's obvious people have already used physical silver as money in the past. You know, the stories from your grandparents about going to the movies with a nickel or something. There is no shortage of granularity when factoring in gold, silver, and copper, so there's no point rehashing an experiment that has already been done. Both options probably have more granularity than actually needed.
Portability:I did not bring up portability because crapcoiners like to pretend that in international trade, one country would just accept an infinite amount of bitcoins from another country while they send them ALL of their natural resources and receive imaginary tokens in return. That's not how international trade works. They would flat out refuse the bitcoins, so the portability argument is way more complicated when real world goods have to be shipped from both countries no matter what and then bitcoin receives no real advantage in the end.
Yes, it's faster to dump bitcoins than metals in some other scenarios, but I also do not consider that as being a positive due to things like the Paretto principle. If all capital eventually congregates in a tiny number of people, which causes the whole capitalist system to collapse, then the facilitation of gigantic capital flights entering and leaving places constantly is going to cause that monopoly board game to come to a conclusion MUCH FASTER, then collapse and have to restart the game by violent revolution again.
Just like the speed of light is needed to act as a governer on the universe, some governers are beneficial in economics to retard globalization, force things more local, and allow local economies to exist at all. Then you have absolutely retarded scenarios like if bitcoin was the world reserve currency, what if a rogue Chinese employee worked at the treasury of your govt and enters a few keystrokes sending your entire nation's GDP to the Guang Dong province? What are you going to do? Get Vitalik to roll back the chain? The portability (aka facilitation of capital flight to subsidize globalization) is a negative in many ways for economics and security. Pretty obvious no nation is going to use such a system as their reserve currency either if one person going insane or comitting espionage can just steal your entire treasury with a mouse click.
I don't think anyone is claiming bitcoin is ready for that kind of international settlements yet. But if it grows to that kind of maturity I'm sure there will be safegaurds in place to stop the noob mistake. In the meantime I can travel with an amount of bitcoin much easier than an amount of gold or especially silver, if you talking any sizeable quantity.
