the property owner has stated that he will not invest more money into his properties as long as they can’t be developed. The owner has no incentive to develop, or even keep up, his property. Rather than working hard to create an enterprise that would benefit everyone through voluntary transactions, the owner may try to sell his property or simply allow it to fall into disrepair. This will deter others from owning property in the area, further exacerbating the problem.
