Lab-grown meat, plant-based "bleeding" burgers (Impossible/Beyond), and dairy-identical proteins are the ultimate resolution to the welfare vs. rights debate. If we can produce meat without a sentient being, the welfarist gets their "suffering-free" product, and the rightist gets their "animal-free" product. The enemy is no longer the farmer; it is the Petri dish and the fermentation vat.
If welfare asks, “Are we treating them nicely?” asks, “Do we have the right to treat them as property at all?”
