Getting people not to eat heavy-carbon-usage-meat at scale might be impactful... like found a lab meat company or something.

I just don't think being a vegetarian has impact... it's something you do to keep consistent with your worldview or morality, not to mitigate climate change.

How can a "no impact" activity like not eating meat scale to be impactful?

An individual's actions does have an impact, albeit a small one. It is measurable (CO2 savings from not eating that meat). Discouraging individuals from participating in individual efforts will prevent the group from achieving scale.

I'm not discouraging an individual from eating meat... I'm encouraging an individual to not buy into the idea that not eating meat will achieve their stated goal.

Isn't the stated goal to reduce their contribution to climate change through eliminating meat related CO2 emissions? Seems like it works.

Doesn’t sound measurable. The whole “don’t eat meat, save the environment” debate should be centred around corn fed beef to begin with

How is it not measurable?
