What I'm telling you is that supply is simply half the picture, and you're neglecting the other half of the picture. If you print a $10 trillion dollar coin, then give it to me and I throw it into a vault, has that increased the price of goods? No. Supply went up, velocity went down commensurately. This is what you're seeing in a macro scale.
Yes the central bank actively manages the money supply, and maintains a consistent 2% inflation rate. Inflation is good for debtors (i.e. most people) as debts are denominated in the currency of the year of issue and repaid with inflated money. So long as wages keep pace (they do [1]) it's generally a benefit.
Money isn't long-term savings. It's a short-term store of value that only needs to be fungible, cheap to transact, and retain the bulk of its value for as long as you hold it. Above all, it just needs to be predictable. Anything else is honestly a non-goal. Your job as a participant in the economy is to spend that money on basic needs or invest it productively.
