Because not only will it be an insult to the series and make it seem cheap if it was either f2p or b2p with cash shop, it would personally kill the kind of immersion I get from playing an elder scrolls title. Just imagine logging in and the first thing that pops up is a window saying deals of the day lol. Or zoning to a new area only to be stopped and reminded I need to buy this area to go on further. Or seeing people with hair styles that werent available in character creation. I think even the console fans would have been like WTF is this.
