It would certainly reduce the pleasure of enjoying all the variety. Who would get to choose which "same" dominated? And if it became a blend of it all -- everyone coffee coloured, wearing all brown clothes of the same shape, living in brown houses, eating brown soup, listening to white noise musac... just can't see it. Humans can't stand boredom and we are irrepressibly inventive. Even if we homogenised everything, diversity would soon re-emerge.
