With currency debasement / inflation, the government is literally taking the value of your money from your account.
They then tax you on the notional gains you made as the denominated price of your house and assets increase.
Remember - it's important to separate money from the value of money. The value is what goods and services it can buy. If $100 could buy all the goods in the world, and they print another $100, then the value halved. If you had $1 in your bank you still have $1 but the value is now $0.50 of what it was based on what you can buy with it.
