Can you actually define what you mean by a closed system please, because checking the definitions on Wikipedia, your analogy fails on all four.
Closed system - Wikipedia, the free encyclopedia
That's fine, but it's still not a closed system.
I leave to the tens of astronauts that have already ejected their detritus for me.
OMFG
you really do not have a clue about economic theory do you..
I never said it would be lower, I said that politics screws up the ability for a true free market to exist. This also means that some prices might indeed be higher. An example here might be the oil 'cartel' of the oil producing states where they exchange political influence for manipulation of the oil prices via OPEC.
Can you explain this statement further, re-reading it, it seems contradictory. So a higher price index can be many things but it is also a constant defined as the efficiency in production and transport? Surely, you mean efficiency is one constant aspect of several other variables that define a higher price index?
Good for you.
