I was reading this question and some of the answers got me thinking. If we have a magic-based society, where for all intents and purposes every being can use magic, and the magic a being can use is limited by a combination of factors that boils down to 'total amount of magic needed' and/or 'effort required to make the magic happen'. I'm not entirely sure if those two aren't the same thing for the purposes of this question, though. Anyways, your average wizard would be able to use their day's limit of magic for create/imbue magical tokens, and we'll say everyone has agreed 10 tokens/day is a good balance between portability and amount of effort. These tokens could be used as magical batteries or as currency. I figure that if a person was hired for 10 tokens/day, they would be expected to put forth the same amount of effort, magical or otherwise, that it took that standard wizard to create the 10 tokens. Is this a feasible method of payment?
In addition, say we have two wizards, A and B. Wizard A is young and can only create 9 tokens/day. Wizard B is older and stronger and can create 11 tokens/day (we'll say he trained his mind in order to reduce the effort it took him to use magic). Wizard A is not likely to be employed by a 10 token job unless they can combine both physical and magical effort to meet that 10 token limit. Wizard B can easily complete the 10 token job, albeit with only a small magical supply left over. Does the fact that physical effort can supplement magical effort invalidate the 10 token/day currency?
Would the fact that the currency is based primarily off magical effort mean some beings could just sit at home, creating 'money', not actually being a part of the social workforce, and is this a bad thing for such an economy?
Lastly, since I have such a vague idea of how economy actually works, what flaws might this system have?
