Agreed. It's the difference between deflationary assets and inflationary currency. Bitcoin's core, fundamental problem is that it's deflationary. Therefore it will never be useful for economic transactions, because any society which fully commits to bitcoin as their currency will have their economy grind to a halt. Why would I buy a new car today when it's going to be cheaper tomorrow?
There's a reason why the Fed targets a ~2% inflation rate for the USD.
