How would that work, exactly?

Spring scales measure weight (Newtons). How would I know when to stop putting matter on the scale? How many Newtons would the scale read when I had loaded 1kg on it and why?

If I count the number of molecules in the rod in France and find it is made up of X molecules, how many molecules would I count out on Titan to make a kilogram? X? If not X, why not?

Mass is not a function of volume. Many materials expand or contract (change volume) based on temperature. Obviously they are not gaining or losing mass based on temperature.

Why not? If the release did not work as planned I'm certain you'd point it out and imply it's evidence Newtonian physics is all wrong. Why doesn't the fact that the release was flawless count against your "variable mass" idea?
