1. I sincerely doubt that the courts will let the law remain unenforced. Let's agree to disagree on that.
2. The reddit post goes into details (which I agree with) about how this law changes the incentives, so real estate agents, sellers, lawyers, etc. are unlikely to want to aid foreign nationals in circumventing it.
3. Selling is a punishment. Everyone gets fined, the house is sold, and the seller cannot get any of the upside from the sale. At best, they break even (minus the fine).
