I have uninstalled every game I have ever pirated that I didn't like and have bought the ones I did like when I could afford them. Once you buy it, tough shit if you don't like it. There isn't a Red Box or rental store for PC games.
I have a huge Steam library of games, but I have pirated a few of the games I was not sure I would like here and there to try them out before I buy them. There is next to nothing for demos on the PC for blockbuster games. They can curb some of this by putting out more demos on the PC. The only other issue for simultaneous PC release would be the pirating problem on the PC. What I would do though is make bad ass DLC like Gay tony and the LatD, but don't do any drastic changes to the game code so that a customer's mods wouldn't be affected. Although DLC does come out later on (most of the time), some mods are truly awesome and could dissuade some folks from picking it up.
If the mods are better than the DLC, then I can see where R* would have a problem with it. I agreed with you, but I have to disagree on the DLC though.
