Absolutely Not. This is not the time period of the 1700s In the western regions of the United States where you had the ability to mark a flag and claim your land without any authority. In other words conducting iconic landmarks to be absurdly divided into the hands of multiple share holders devalues the aspects of what the United States constitution had evidently implied. National Historic landmarks are under the behalf of federal ownership due to its conditional matters and its environmental conditions. Think if the Grand Canyon were to be on the market for property possession in individual sections the purchases would boom and multiple urban like structures will be revisited there devaluing the aspect of NATIONAL LANDMARKS TO ABSURB NATURE AND THE ENVIRONMENT. My point being is increasing the amount of federal lands that are urgent to be at a safe status shall be left to that particular designation as implement. Selling off properties to market buyers and entrepreneurs looking to promote residential properties and urbanization would hinder the factor for environmental preservation and damage the habitats/ecosystems of our crucial wild life community as well. Thank you for your time.
