It's been my experience that the farther you let an undesirable process proceed, the higher the chance that it will reach its undesirable conclusion. The enforcers will make decisions based on sunk costs; there will be more loopholes for the grifters to exploit; the time demands of due process will let them manipulate to their benefit; and there will be higher consequences for disrupting the status quo (e.g. there will be people actual living in the buildings already).
