I find myself in general agreement but I wonder what second order issues would come about. Will we see companies listing an old game for a trillion dollars a copy just to keep rights?

I think Japan has an interesting model though for abandonware, at least when the copyright owner can't be tracked down: anyone can sell an old game, but a portion of the income goes into an escrow account in case the copyright holder is located.
