I'm fully supportive of the Berg's doing what they wish with their private property. That is their right as a property owner. I do not believe, however, that others should be forced to subsidize their decision.
Let's say that I make a different decision for my property; that I'm not presumptuous enough to believe I know today what is best for my family/heirs 50 or 100 years from now, and trust they will manage the property in a manner that is most beneficial to them, and I chose to not limit or restrict their options. In that case, the government punishes me with income, estate and other taxes. If I had made the same decisions as the Bergs, my decision would be subsidized, or free from the aforementioned taxes.
I don't believe the government should subsidize one person's decision and punish another person's opposite decision on the future of their property. Leave us free to make our own property decisions without government interference.
