The only thing Friend codes theoretically limits is socializing with people you don't already know. It's not that unsensible. Everything else gaming related could be done without friend codes (this is what rivals systems are supposed to be about), but it can only be gaming related.
True it hasn't been publicized or implemented very well, but it's gaming sites like 1up that perpetuate the myth that online Nintendo gaming can ONLY be done with friend codes. And that somehow friend codes destroy gaming, kinda like how phone numbers destroy wireless communication. Oh wait... they don't.
