All they can do is discourage through various means since in a very technical sense your computer has to download it to display it. All they can do is pretty much what they do now, not provide links to directly download videos, and block clients that allow videos to be saved. (Un)fortunately, a lot of clients actually lie to the server and claim to be either the flash plugin or one of the supported mobile browsers to download videos.
It's basically like the jailbreak community and Apple in some ways. Google can keep trying to block it, but people can and will find ways to do it anyway.
