They did do this with ME2. It's called the Cerberus Network, and it's for all the free DLC that you get with the game. Buy the game new, you get access to the Cerberus Network for new weapons, quests, etc. Buy the game used, you gotta pay up for a Cerberus Network pass.
TOR is an MMO, so I don't even know why you're bringing that up.
So wait until it's economical to buy it or do without. It's the same argument I have against people who try to justify piracy: if you're not willing to pay the asking price, then don't play the game.
You're flat out wrong. Buy new, you get the pass. Buy used, you pay 10 extra. Nobody's charging you 10 bucks on top of the 60 dollar new-and-shiny retail price.
Did you buy those games new or used? Because if you bought them new, you wouldn't have been hit with any extra fees anyway, so it would have been exactly the same. If you bought those games used, then the publisher wouldn't have counted that as a sale anyway, because they didn't make any profit off of your purchase; they wouldn't notice a drop in sales because they don't keep track of used sales anyway.
There are more important things in the world to be scared of than online fees for video games.
