You are joking, but current organization of humans is very wasteful and limiting to development. Apart from the resource burning consumerism, growing complexity of knowledge and technology would probably end up requiring segregation and specialization either way, so that some people would raise children and other people would devote their lifetimes to complex fields of knowledge, which of course implies an authority would have to provide for people. None of this have to be more limiting to almost everyone's personal freedoms than they are already limited today though.
