I wonder who will buy it. Having read the details in the BBC link about what you can't do with it, it seems there's no return on the investment and certainly no opportunity to make any profit from it unless the land price rises in time.
Also if it's inundated with people leaving litter like so many other areas have been lately, as Landowner, would it fall to you to finance an ongoing clean-up operation?
