You can build a fence to keep your dog in. You cannot build one to purposefully hurt your neighbor.

"Purposefully hurt your neighbor"? What kind of standard is that? What if he plants a row of trees to "purposefully hurt his neighbor"? Is that okay, and who gets to decide? You?

If someone builds a Picnic Grove next to your property, your home or vacation spot, you have the right to expect his use will not be too obnoxious to you. What is obnoxious is obnoxious within reasonable standards, but say if he has a multi-kilo-watt sound system blaring long into the night -- that is obnoxious, and can reasonably be restricted, and such restrictions are the duty of local government, so that adjoining owners are not a constant war with one another.

The word "PROPER" is key to understanding property rights. As owner of property you do not have the right to poison the creek that runs through it, or poison your own well because that may affect the the ground water of your neighbors.
