Not exactly answering your question, but I think this argument (and follow up question) neglect an important aspect of your contribution.
Having more vegetarian and vegan people creates an incentive to develop meat substitutes (e.g. beyond meat, impossible). If those substitutes, and especially clean meat, will hold up to their promise (i.e. cheaper, taste just as good, and be at least as healthy as regular meat), it will have the potential to change the meat industry dramatically. In this situation, way more people may become vegetarian or vegan due to economical or health reasons.
