It's not about complexity, its about diversity.
Problem is a lot of producers doesn't seem to invest much of themselves/are too involved in sceneist conventions. Not saying going all expressionist, but most producers are kinda interchangeable, ehh, 'producer' types. We need more difficult characters. Or people from other backgrounds, visual art, even traditional art. There were people like that in the german techno scene earlier, I believe it did make a difference in approach. I mean there are tens of thousands of techno/house dudes booting up their studio to make a "banger" now; this is not the right approach.
Still it cannot go to far, individualist artistery can end up in noodly IDM crap, so the functionalist, conservative "130 bpm" restrictions is good to keep things in check and impose a conservative, ritualistic aspect, something which is (still) unique for electronic dance music, broadly speaking.
