The question of whether you can get by without meat at all then seems quite similar to the question of whether you can get by without any fruits or vegetables… Do you see a relevant disanalogy?
According to Wikipedia, the national dietitians’ associations of the USA, Canada, and Australia claim that well-planned vegan diets are nutritionally adequate for everyone, while the German Society for Nutrition warns against it, especially for children, the elderly, and the pregnant. On balance, this is much more positive than I imagine their opinions would be on a carnivorous + supplementation diet.
There are surveys about this – for example U.S. News & World Report’s’s annual survey of dietitians. Vegan diets are always rated as much more healthful than meat heavy diets like Paleo, and presumably paleo in turn is better than “meat + supplements”.
So transitively, it seems like experts do perceive a relevant disanalogy.
