If Steam went out of business or they had a new policy that stated you could only play the game for 5 years lets say even for existing games in your library I think many would turn to piracy of the same titles.
To be honest most of the games I've bought on Steam have been brilliantly priced, well below normal console game prices. I'm amazed at the huge library I have for so little money. The ability to run the same games on my various pc's and older laptop is brilliant. I'd find it hard to get angry with Steam for the sheer brilliance of the service they have provided.
I personally think in such an instance Steam would come up with a fair policy to allow you to backup your games and make install discs or something similar.
