It's actually a huge slippery slope. The common good is a common lure to surrender personal liberty. While the argument may be a little dystopian and represent a worst-case scenario, this represents a step toward the government saying what can and cannot be done with your body. I always have and always will opt-in as an organ donor, as I have no further use for my body if dead and would like it to go to some use. That said, tearing apart someone's corpse for spare parts should never be anything but opt-out, especially as there are more than likely people who object on moral and/or religious grounds and are not aware of this policy change. Forgetting to check that "skip this" box should not lead to a violation of people's religious/moral beliefs.
