One alternative would be for you to follow the prescription, "find out why the fence was put there, then I may allow you to remove it". Investigate what's on the other side of the fence, without tearing it down (this might involve experimentally re-discovering the theory of radiation, depending on the current state of mankind's knowledge). Then go back to the authority and report that the fence seems to be there to contain radioactive waste with a million-year half-life. Armed with this information, the authority will be in a better position to determine whether or not to allow you to tear down the fence.
