My building has just replaced the lift systems with brand new "smart lifts" and the buttons are gone completely, only the emergency button remains. This has made me err more towards the placebo button theory though, being in one of the button-less lifts feels like being trapped in a dystopian nightmare with computers running everything, the one's run by the same computer that haven't had the buttons removed yet feel much safer. Also, these new "smart lifts" are horrible, much slower than the previous ones and seemingly not built with the concept that 1 elevator request could involve multiple people travelling.
