As much as I like the concept, there are flaws in the design as presented by @flauwy in the comments. Also, name-squatting is a thing that has been done in the past and nobody really complained about it. After all, it goes down to money and how much is the buyer willing to pay. If there was a domain name that a company really wanted, they just bought it. If they didn't, seems like they didn't want it that much really.
