Whey protein is not of questionable utility, it's used heavily by athletes worldwide, to great effect. Other proteins can be used, but it's the most common by far. The comparison might still not be perfect, but OPs point about needing a well-balanced diet is still relevant and important to this discussion. We don't get all our nutrients from a single source, especially not meat. So not getting all our nutrients from lab-grown meat isn't a problem. We'll get them from somewhere else. Unless you know there is a specific nutrient in meat, which we don't get from any other source, which lab grown meat won't replicate. However, that's unlikely or vegans would all be dead.
