In principle, I agree. But I haven't lost any CDs or manuals; if anything, they've become collectible items. Importantly, I have control over them; and no-cd cracks aren't exactly rare.

But with servers, there is no control. And it seems an obvious further development of DRM is to host some of the application code remotely, so that no simple workaround will be available to your children, should they want to see what games were like in your youth.
