> So bitcoin can't be devalued by "printing" fake "bills." That's a good prerequisite, but it's not a practical improvement for me over the current currencies.

Well, the value in bitcoin is that it can't be printed by anyone, even the goverments, uncontrollably - there will be only specific amount at max in circulation at specific time.

This might not be valuable to you, but it certainly will be for many else. Many people don't like the thing that goverments keep devaluing their fiat currencies.
