"Unenforced"? No, no -- the $10,000 fine will be collected. It's just the forced sale that might not occur if the superior courts are busy (and they are!), and if it does occur, the foreign nearly-buyer will be out $10,000. There's no need to encourage baseless Reddit speculation, just read the law itself -- I've linked it, you've linked it -- and reason about how the government will act based on the last 30 years of government (in)action.
