umm.... you dont lose the games... maybe your game saves but not your games.
Downloadable games are synced to your ID. You delete the game off your HDD you can download that game at a later date and repeat this process as many times as you want.
If you want to lend a game you can do two things, have your friend log into your ID on their console and download it or you login to their console and download it. Of course there are download limits but who cares, if you share your games that much you deserve to pay for more copies of that game.
I doubt Sony will be taking old games down from the PSN. I dont see them doing it. Microsoft is doing it because they are to cheap to fork out for larger HDDs or better servers for their LIVE service.
