No one owns any land, you just rent it from The Federal Government. Why do you think you need permission to dig on "your own" land? You just rent use of the surface area.
Except for one piece of info that Karl Lentz and others brought out into the open. Your land is your property, that is, proper to you. If you call it land, real estate, or something else, you aren't calling it your property.
If the government comes after you, take them to court. The government can't get on the stand and say anything.
Take the man to court who is using his governmental authority to take your property from you. He is doing it, not the government.
If anyone can provide proof that he is the owner of the property, let him come forward and prove it. When you provide proof, it's your property... to do with as you please.
If the government man comes forward and states that he has evidence that the government is the owner, let the government come forward, get on the stand and state how you are doing a wrong.
As it turns out, when people are adamant like this, and don't give in to government and the courts who are trying to badger them, that government often backs down and simply places some kind of "lien" against the property.
The answer to a lien against the property is to place it into trust with yourself as the trustee, and never sell it. If you want to sell it, make the buyer-to-be the successor trustee, and then you resign as trustee.
The most successful trust method I have seen, with the least amount of worries, is found at

If they physically remove you from your property, you have a suit action against the people man-to-man who removed you, for touching you without your permission. You might lose the property, but you will gain the $millions from them in the suit. If you are adamant, they will back down once they understand what you are doing.
Listen. Even though it seems jumbled, put your thinking cap on and listen -
