My post was not stating that digital currencies are inherently, "magically" non-inflationary.

To me, it sounds like someone is either ignorant or arguing in bad faith for them to suggest that there are no digital currencies which are non-inflationary. BTC will never exceed 21 million bitcoins in circulation.

To address your other concern - the "problem" being addressed is a private company seizing your money over the contents of your speech. With self-custody of digital currencies like Bitcoin, it is not possible for third parties to expropriate your funds, provided you have protected your private key.
