That's fair enough. In terms of the price for unique + human readable + decentralised + stores relevant records... I think that's pretty much as cheap as it gets in the off-ICANN world. And as cheap as it gets still isn't that cheap.

I'm skeptical that anything not human-readable can scale, for relays, mints, or anything of the like. But yes it would be nice to have a QR-based network of sorts, that's a cool idea.
