That's a good quote. There is this false assumption that people naturally want to optimize for physical health at all cost. Even of that was possible, it's obvious from people's behavior that it's not the case. But somehow the threat of negative health consequences is still a powerful rhetorical device to convince others to do what you say. We need to be more open about the fact that health an longevity are not people's only goals, and that nobody looking only through the narrow lens of physical health should be telling us what to do.<p>Somehow I find it ironic that this comes from Marx who I associate with suppressing the individual for collective "good". I assume that's because i don't understand him very well.
