You're right, but I think you're conflating arguments.

Meat eaters should be proud to wear leather, eat byproduct, etc. Anything else would be waste, and it's shameful to act as you describe.

But vegans want all of it to stop. There's nothing to waste to the animal isn't killed. Well, until it does naturally. There's nothing to waste if the animal isn't born though. And it wouldn't be born if we didn't have a culture of harvesting their bodies.
