The idea that deflation is built into Bitcoin is exactly equivalent to saying "the real value of bitcoin will always increase" which is an absurd premise.

Bitcoin is deflationary only in a hybrid Keynsian - Austrian worldview. In the Keynsian worldview it cannot by definition be deflationary because that would mean that the value is always increasing which is just kind of a mad thing to believe. In the Austrian worldview it is not deflationary because the amount of Bitcoin is always increasing by design. Only if you accept the Austrian framing of "deflation is when you decrease the money supply" together with the Keynsian framing of "money supply is measured in real terms not nominal" do you arrive at the idea that it could be deflationary, and there are exactly zero economists who believe both of these things.
