> I don't think it's defeatism at all, by my estimation it will do very little or nothing at all, while creating a hassle for everyone. I guess I could be wrong about that, but that's what I'd expect.

We have a longstanding counterexample: Trademarks. You can't register a trademark without using it and you can't sell it.

And the latter is practically in name only -- you can sell the "goodwill" associated with the trademark and transfer the trademark with it.

Yet with as little as that, we don't have companies squatting on millions of trademarks or shaking down small businesses who just want to use a name nobody is already using.
