I agree with your logic, from a pure logic standpoint. But are we allowed to draw a line against foreign investment from sworn enemies, human rights violators, communists, etc? Are we allowed to stand up for what we believe or do we have to be faithful to pure logic and deny our sovereignty?So you'll wield the power of gov't against the former owners of Smithfield farms to tell them who they can and can't sell to? All your non-interference s/gov't is tyranny/free market principal are outweighed by cheaper pork? You come over to my side that capitalism is harmful without regulation at a pretty low price once it affects your wallet, apparently.
I've already given you a fix. They can't take the farms or land home with them. We have methods within the law to reclaim property if it becomes an issue. We've frozen/seized assets of Russians over the Ukraine thing. We have import/export laws. We even have a law that allows for the direct seizure of food stockpiles from private sources in war time/extreme emergencies (every now and then INGO runs around the table flailing arms about that one). I don't see Americans starving to death due to the lack of pig kidneys yet, so we're probably not to the point it's an issue, but there are a multitude of remedies available that don't require a ban on foreign investment.
