That’s extreme and I think most of your point comes from a belief in being vegan as an ethical way of life rather than from a genuine willingness to limit people environmental impact.

The proper way to frame it provided someone has no desire to be vegetarian would be limit your consumption of meat - only eat red meat as an exceptional treat and favour poultry a few times a week - and switch to plant based milk.

Eggs and honey are very much fine as is cheese given the average per individual amount eaten per year.
