I think that's part of the Kraftwerk play book that Daft Punk have previously acknowledged. Obviously Kraftwerk's robots look like them to a certain degree, so Daft Punk have taken the on stage anonymity further but the anti-pop star thing is pure Kraftwerk. There was famously only one way to contact Kraftwerk, via a phone at their studio with ringer mechanism removed. If you had the number, only given out by their lawyer, you rang a preset time of day when the handset would be lifted... if you were lucky.
