But does this really give you non-conservation? Doesn't your remark just clarify that non-conservation comes from ignoring most of the space of possible ownership until someone bothers to go there?
I mean, there is clearly a difference between the value of (sensible) financial derivatives and the value of the death star to the imperial court in the Star wars universe.
So the connection to physical reality clearly matters somehow.
A meta-fund that owns equity in a fund that invests in securities issued by owners of multiple pop-culture IP franchises? No problem.
In any case, I don't see why positions and correlations between different particles shouldn't be considered "real", so that's arbitrary stacking of ownership brought down to earth.
In fact, wasn't subprime to a large degree about falsely claimed correlations? That is to say the derivatives implicitly assumed things that weren't true, or in other words secretly left reality behind.
