What I mean is that I don't have any control over whether it dies. People want to eat it, and they are not amenable to the idea they shouldn't. But they are amenable to the idea that it shouldn't be tortured beforehand. Reduction of harm is always good even if it's not perfect.
I also said I'm not sure that it's possible for everyone to live healthfully without consuming some animal products. I personally haven't been able to maintain a vegan diet for longer than two months any of the many times I've tried, so I'm not in a position to lecture anyone on what they eat.
Overall, I think a baby steps approach is the most realistically achievable path to a potential future of zero harm. (I don't say vegan here because I don't object to symbiotic forms of exploitation such as pet ownership or beekeeping.)
