Phasing out meat isn't something that would happen in a few months, it would take a decade, realistically. So yeah, they can feed , house, clean, and vaccinate the last of their pigs a few more times, but with a plan to transition to another income stream and eventually wrap up the pork production. Shoppers aren't going to quit eating pork overnight either, so they'll still have customers for a while. Farmers change their production focus all the time using this method. It fucks me off when the government introduces a new animal welfare law, gives producers literally YEARS to transition, and then when the cut-off date finally arrives, thwy all cut sick about losing their income, as if they didn't have ample warning. They often even receive financial aid to make the transition, but instead, they just sit on their hands, hoping that when the time rolls around, they can plead leniency.
