Umm...why are people always against headsets? In my honest opinion it is flat-out ridiculous that people don't want them. I mean seriously, Nintendo, if they make one, will never allow you to talk to randoms. It'll just be your friends. And, if you don't want to talk to your friends currently...take off your headset and don't...
And your second point is "I would rather just use the pc or talk on the phone, it's easier."
Well, that's just a false statement. If the wii were to use bluetooth headsets it would just be cutting out the middle man and be no way difficult. It would actually, and this is the kicker, be easier ....really? Easier?
