My entire point is that while there are absolute properties of spacetime, all we know are rough measurements and all our derived laws are calculated as ratios and relations between different properties, which is precisely why it's possible to insert scaling factors in our math and change every number with no visible effect in behavior despite drastic changes under the hood.
Like how a few physicists describe expansion of the universe as objects in the universe shrinking, and the math ends up essentially identical. Because both formulas describe the exact same ratios and proportions so the behavior is the same but the mechanics causing it is different and we can't not tell the difference.
Okay, see, that makes a lot more sense.
