I, personally, do not care if factory farming causes suffering and support cheap, nutritious and convenient food by whatever means is necessary. The people who want to ban it are insensitive threats to human comfort IMHO.

But if it is a problem that needs to be solved, breeding the animals to enjoy it is a much easier solution than synthetic meat. We've had the technology to change animal behaviour through breeding for longer than we've had history. If people want them to get a kick out of being caged and slaughtered then that is doable. easier and would have been faster to accomplish than growing meat in a jar, anyway. I think it is a waste of time, but it is better than laws restricting food production.
