The thing about Xbox Live is that you have to pay for things you don't want. There are people that are fine with paying a bit more for things such as EPSN and exclusive map pack. But there are also many other people that only care for the online gaming part. It might not be a big deal to some people to save an extra 10 or 20. Money is money, and some people would prefer to not pay for things that they don't want.
I don't think MS will ever have the option to pay for just LIVE. Its either premium or nothing.
