If you own the property, you can leave it where it is and ignore it. But, if that property is a boatyard...then you are losing money because the space it occupies may be worth $5,000+ per year as storage for another paying customer.
So how do you get rid of it? Well...first you need to chop it up, crush it, bring in some big equipment or a dozen men with Sawzalls. Costs money. Or you can push it off into the water, oops, MARPOL violation, costs money. Or you can try to bury it, if you can find a landfill to take it, and with all the concerns about toxins and the like...You can't give it to a landfill unless you remove the lead keel, the bottom paint, and any other toxins first.
So, you have to try finding some sucker to buy it, who thinks they can fix it up for less than the cost of buying a boat that's in sailing condition.
I'm not saying there are no real bargains, but usually when there's that much damage you can see, there's more you can't. And unless someone is already skilled at fiberglass repair and hull painting, doesn't mind scrounging for rigging and sails that might or might not fit, trusts the home-painted engine...Some folks can get a bargain, more can get burned.
Usually we put an ad on eBay and sell it to some Portugee looking for a bargain priced boat in America.
