Market value is having someone else have control over the value of what you control. Market value may not be centralized, but it is the definition of something you do not control. This is my point. You cannot have full control over something that's value is dictated by an external entity, the entity being the market in this case. The concept of having "full sovereignty" over something that you don't control the value of, and the only purpose is to exchange for something of value, is non-sensical.
