Relative value comes from supply and demand. Central banks are not just devaluing currency with the printing press, they are functionally changing and corroding it.

It's as if they had the power to make your computer worse just by printing some more, which is obviously not the case for computers. Yes, the relative value of computers changes if you shit out a lot of them, due to basic supply and demand.

They do however retain the same absolute functionality no matter how many there are.

This is not the case with fiat currency. If you print too much of it fiat loses all of its functionality as money and this happens on a gradient, e.g. the more you print the more useless your currency becomes.

If you create an infinite amount of computers the only thing that will happen is that everybody will be able to have a pretty nice tool.
