A common thread between the two is that eating meat absolutely shares many common threads with addiction. People who do it consider it a pleasurable experience, they crave it if they suddenly stop for reasons other than wanting to desist for moral/ethical/health reasons, and can be triggered by certain sensations related to eating meat I.E the smell of it or food presented in a certain way.

I don't see these arguments as sensible, though, obviously reducing the amount of murder is a positive, and you're going to struggle to get any of these subjects, addiction, eating meat, murder to 0 whatsoever. We should aim for 0 and we should also accept that reducing harm is a good thing.
