If a man cannot build a fence on his property because you have prevented him, you have stolen his property.
If I can see your house, I am not stealing your house. If I can see your car, I am not stealing your car. If I can see your lake, I am not stealing your lake.
You have no right to see anything. You have no rights to an unchanging view and you have no right to property value for that matter.
To use force to obtain/retain a view is immoral. You know it but your hatred of this swine obscures your thinking.
