Maybe just stop being stupid and either:
Pay for XBL
or
Play on PC
Your problem is solved for PC as there usually are DVD versions of expansions released, or you can just have steam download and install everything for free.
Honestly the only logical reason I can find for someone to play on x360 is if they play multiplayer games and they want to play with other friends who only play on x360.
Skyrim is a single player game. You can plug in your xbox controller and play Skyrim on the PC exactly as it's played on console, except you have access to mods, community bugfixes etc. I personally switch my PC output to my LCD TV, and lay on my bed playing it with my x360 controller, it's essentially playing on x360 without all the limitations and problems that come with the console and XBL.
Why are there people like you who can't understand that people like different things for different reasons?
Some like xbox, some like ps3, some like the pc and some like broccoli.
Get off your high horse, stop thinking your way is the best way, and let it go.
Really. Just let it go.
