We'll see if that's true the day all the "minor" limitations are solved.
Today bitcoins cannot be spent, due to technical limitations and psychological ones (high fluctuations make it impossible to know how much you are really spending)
Bitcoins can be stolen by simply hacking (or losing) a device, your money can't, unless it's cash.
But you usually don't keep all your money in cash in the same place, as you do with bitcoins.
etc. etc.
