Because what you're really complaining about is that all the games act like they are the *same* game and playing different games simultaneously is somehow wrong.
If Steam knows which games you are playing, then what you want, is to be able to log in however many times you want, and play only _one_ instance of each game.
The problem of course, is that everything else associated with Steam (buddies, achievements, etc) is not set up to do that. Even with the proposed solution, how will messaging work? Accounts within accounts? This whole inconvenience is looked upon as a feature to software developers. See those 2-pack combo deals in the store?
Given how slow Valve operates (HL3 anyone) I would place the likelihood of this ever happening at zero. Go with whatever your Plan B is.
