I don't necessarily agree with the LLM moral objection, but this point of view is unconvincing. Change the topic to say, slavery, and the "I feel bad for those who reject slavery on moral grounds, they'll fall behind..." argument becomes fairly absurd.
You're essentially saying the very concept of a moral objection is to be pitied. Maybe you believe that's true but I'd say that reflects poorly on our values today.
No, he's saying this specific moral objection is to be pitied.
When I say "I feel bad for people who feel a need to own guns", I'm not saying I feel bad for people who feel a need to lock their doors at night.
