And you still don't get the distinction between mass as physical quantity and the unit of measurement to express that quantity in numbers.

It's also true that G has different numerical values in units of kg,m,s, or g,cm,s, or slugs,feet,fortnights, but these are all the same value.
Mass doesn't change if G does.

Exactly my point.
Whether G is a universal constant or not, it has absolutely no bearing on the unit kilogram.
