Perhaps if they try to force you to arbitration you can push back and demand proof that you agreed to their terms, which is conveniently achieved by creating an account.
Arguably, if the court ends up agreeing that you did have an account and that Valve needs to give control of it back to you, would that not be evidence that you had agreed to the terms, then broken them by rejecting arbitration? (Leading to Valve being able to take your account away because you broke the ToS.)
