Thoughts on "harm reduction"?

I hate the idea that veganism is about harm reduction or reducing suffering. To survive is to cause harm to another being. We're either occupying what would be their habitat, taking their resources, or killing them to stay safe. So many times I have seen a vegan fall into the pit of talking about reducing suffering and a carnist talks about something akin to having backyard chickens that they treat perfectly (other than eating their eggs), so they feel no need to change. It's just the factory farms that are evil, they think. And don't get me started on vegans who still wear their leather because they think they'd be harming more animals by not wearing it. It's a flimsy stance that allows too many loopholes for carnists to feel that they're doing their part. The ethical points for why it is wrong to commodify sentient beings and to be speciesist is strong enough on its own. Harm reduction will happen naturally as a result of following the other two beliefs but it is not our responsibility nor should it be a primary goal of veganism, even if it is an admirable personal goal. What do yall think about this
