To be clear, I don't think bitcoin that good a currency either. I wanted to point out that the deflationary aspect is an arbitrary (and I think stupid) restriction.

You are right, modern fiat currencies can adapt and that is the main thing bitcoin lacks. My understanding was that happened mainly as a result of central banks who can adjust all kinds of parameters. This is antithetical to Bitcoin's entire design principles, let alone the underlying technology (which could me modified to accept some parameters modifications from a board of governors).

Normal banks can't do that. To the extent that they do cause things to happen, can't they do that with Bitcoins. I.e. issue loans and collect payments with them.
