Money is pure value.
Yes money is a pure value, but it is for now. So later after bitcoin have affected they surely money will slowly replace by bitcoin then it will affect all world to use this kind of payment. Just wait for that time to booming then all people will be affected where the new era is coming
There is a common misconception that money is not value, because it can not be eaten etc. But, all value is
one individual's preference for one thing over another, which includes money. Therefore, money is value just like other things.
I agree that value is subjective, means utility and can be compared on the basis of an individual's preference of one thing over another. But I don't agree that money can be judged that simple. One of the fundamentals of the subjective value theory that you make reference to here is the notion of diminishing marginal utility. Money apparently doesn't conform to this notion, which can be explained only by the fact that money doesn't possess value per se. It is just an intermediary for things that can be bought with it...
