You have cause and effect confused. They buy the property because of the goodwill, they can't get it any other way, they know they will destroy it but goodwill doesn't necessarily show up on the balance sheet, whereas the result of burning that goodwill will show up on the balance sheet.
Well, no, in what way would I have this confused? I state they always manage to lose goodwill because it is in their nature to do things which alienate customers. I'm not saying anything about the why of it, just that they always do so.
