"I have a hard time figuring out how the value of ether makes sense. I need to study up on the details, but the abstract is you need ether to "execute code". So if ether is too highly priced, no one will use it to execute code, and if it's too low, then miners won't mine the contracts. So the amount of ether needed to execute a contract or part of a program seems like it needs to float. Not sure if they are accounting for this. This could be something like mining fees in some sense."
