As a landowner i can attest to the fact that we don't have as much freedom to do what we want with our own land as we sometimes would like to think. Furthermore, there can sometimes be a big difference between exercising one's rights of ownership and being a first class poopie head. You may do things that are well within your rights, but royally piss off everyone around you. When/if something bad happens to you or your property, you are much less likely to get help or sympathy.

Also some of the most flagrant examples of tresspassing that I am personally aware of have been committed by large landowners who essentially think that they are above the law. So, land ownership doesn't make one a saint who is always victimized by the landless.

If this guy is actually doing all the things that the poster claims, there may actually may be many legal actions that can be taken to give him an attitude adjustment. For example, as some folks have stated, in many instances, you DO NOT have the right to turn your property into a big off road track if you are damaging a watershed and/or causing soil erosion, especially if the damage carries over to neighborhing properties.
