What I mean is that 1000 kg and 1 000 000 g depict the *exact same quantity*!!!
Yes, they indicate the same amount of stuff, but visualization cannot be done with one million units. However, one can imagine 10x10x10 units.
Remember that it was J.Paul Getty who said,"If you can count all your money, you don't have a billion dollars."
Carl Sagan made a living helping people visualize large quantities precisely because people generally can't.
The whole argument is rhetorical, academic, and parochial anyway, because, as you say, there is no real distinction between them.
