In response to your edit, I don't know how you can claim that "real" (according to who? you?) inflation is somehow divorced from the purchasing power of a dollar. What matters to most humans is how far their wages go at the shop. Hand-waving at money supply and "total amount of stuff" without reference to prices makes as much sense as arguing "Well obviously daily commutes were shorter in 2019 than 1919 because cars are much faster than horses. Just look at my chart of relative top speeds!"
