(Mind that I have lots of Steam account games too)
If we gamers make the decision to buy a given used game and the new one only costs ten dollars more, just spend the extra ten dollars and get it new. If you can afford to buy it for 50 dollars, you can afford to buy it for 60, just means you don't also stop at Jack in the Box on the way home ;)
But yeah, you (OP) wouldn't be fine if SOPA passes as many fun and informative websites would be taken down.
