I just want to trade games permanently. I have a whole category in my library full of shit I'll never touch again.
I thought Steam already has a trading system?
I've been a PC gamer since 1994 and I still barely know my way around Steam..
You can only trade games you have in your "inventory", in other words they aren't tied to your account yet. Like if you get a free copy of Portal 2, you can choose to add it to your library or trade it, but not both.
