I voted ‘no’ for the following reasons:
POI aren’t permanent. And if a person requested it, and it was approved, and they still own the land, then, imo, it should stay. Even if the land is put up for sale.
Furthermore, imo, POI are markers for builds, not land, so if the next owner buys land with the same build on it, then why should the POI be removed?
For example, if I had a pizza business and has a big sign out front, and I sold the business to a new owner that intended to run the same business, the sign would go along for the sale right?
If the new owner decided instead to sell Chinese food, then the sign would no longer be applicable, in fact it would be detrimental to the business, and would or should then be changed or removed.
POI’s, imo, are just that, simply map labels to actual places of interest (POI) for visitors, so if they have any monetary value at all it is de minimis. And if the scene still exists after a sale, then the POI should in fact still be valid.
So, imo, I doubt that somehow could really profit, beyond what they normally would, simply because the land sold has POI designation.
More than that, once the land sold, and if the community really felt the new owner isn’t doing what is necessary to maintain a POI marker, then they can easily put in a proposal to have it removed at that time, and it would be gone in a week or so. So I doubt that any buyer would assign any real value to a POI marker because: it isn’t owned, not permanent, and can be quicky revoked by the community.
