In my mind the low transaction cost is a feature in that you can make snap decisions (or in many cases not make them at all) without having to explain yourself.
What I mean is that if I had to itemize every gallon of water, every kilowatt-hour (or watt-hour) of electricity, every cubic foot of natural gas, every byte I upload or download, etc etc etc to come up with their "true" values I wouldn't have enough hours in the day to do 10% of what I normally do.
So I guess my question is this: at what level of granularity is this being proposed? And if it's anything less than "full granularity" why? What I mean is why should utilities be any less valued than phone apps? I need that first gallon of water WAY more than I need Angry Birds, so it seems to me like that needs to be accounted for. But that would be exhausting. I can't see a way for me to take this proposal really seriously AND not simultaneously want to hang myself.
I think it's an interesting idea to be sure, and it's fun to think about. But I really hope I don't have to tell everyone how much I like water or electricity or whatever.
The low transaction cost of money is partly a result of how deeply embedded it is in our social and institutional practices. I don't think it is an essential feature of money itself; other practices might come to fill similar roles. I would also suggest that the opacity of traditional currencies to certain forms of value also has a crippling effect on our economy. Economics talks about these as "externalities", but they are best understood as values that aren't represented in our trades. I'm not claiming that Strangecoin can capture all externalities, or even that it catches the important ones, but only that it captures some dimension of value that is hidden in traditional currencies.
