I don't know how much was live but look at how many people go see Daft Punk and they are probably not even in the country for their shows. Much less playing anything live
it's definitely the 2 daft punk dudes in those robot suits.
people that go to an electronic music show expecting a rock show will be disappointed every time. the music wasn't written "live" and wasn't recorded "live" (for the most part) - why should it be performed "live"? i can't decide if it's more disengeneous or ignorant to think that it should be performed in the same way as rock music.
admittedly, some artists are partially to blame. instead of embracing the genre for what it is - live remixing, with maybe vocals or a guitar "live" on top - they try to make it into a rock show. on the other hand, watching someone behind a computer/mixer/etc isn't very visually compelling
hence the brilliance of daft punk's show: we aren't that interesting to watch while we make the music, so here, have a mind-blowing light show
hip-hop has live music in the recodings, but no one ever complains that at concerts it's always a DJ and not a full band (or alternately, praise them for having a live drummer or whatever).
