>what other options are there?
Troc/barter.
The problem is that everyone values objects differently.
And we still that with cash. For example I did a 4 day job on a single computer and it cost 120 euros for the customer, other people would either never had done work on it because they see it has non profitable due to the cost of living/time passed to solve the problem. Or it would have costed a lot more than what I asked for.

Does not change the problem of being able to exchange the paper between people, thus it makes fraud possible, if that's a problem to you of course. Imo people should be free to do what they want with their retribution.
This is what happens with checks these days when people do not want to pay in cash. Multiple checks with certain amounts without names are made and then people either exchange them with other people or pay with more than one check.

>precious metals
Precious metals or precious gems are also arbitrarily evaluated.

>cryptocurrency
-When the internet will be fully anonymous
-When computer will run GPL software/hardware from top to bottom
-When the power used to mine isn't waisted into nothingness, like for example "World Community Grid" and other projects.
Tbh I'd go into cryptocurrency if they would implement such function. WCG-Coins. Coins in which computation results were made for public research projects.


There is no real definitive solution to the currency system. The only system that works is when a majority of people accepts it. Like most system.
