This is certainly an interesting proposition and good luck to Aaron and his team with taking it forward. But I don’t want a Netflix card or a Geico card, I want a Netflix identity and a Geico identity. Not just a card number, but a name and address and e-mail and… reputation. If I use a different card number at Ashley Madison and William Hill, then hackers (or, worse still, marketers) can still see that the name and address is the same and then reasonably conclude the same person is behind both usernames.

We need to make it hard for attackers of any kind to do this kind of thing.
