The issue is that mean production has externalities (e.g. climate, labor conditions, environment, biodiversity, animal suffering), some of which we will soon no longer be able to ignore. We can insist on ignoring the problems for as long as possible but that's still not forever. Eventually we will have to start paying the "real price", which would mean that meat gets a lot more expensive, as it used to be a few hundred years ago. But people will not like paying 3x for meat. They will have to eat less of it or look for alternatives, including insect-based foods. Such alternatives shouldn't be blanket-banned without good reason. (Not that I believe lab mean will be cheaper than animal meat any time soon)
