Interesting thoughts from both of them however like he said, we use this stuff everyday and it's not crucial or a big benefit in any of the current scenarios (flyer miles, credit points etc).
What can be said though I guess is that barriers to entry to issue you r own token for all kinds of purposes becomes much more easy plus it costs close to nothing. In addition there is the possibility that the transfer of those tokens becomes accountable / public.
What I found particularly convincing though was the possibility to trade between user issued assets and price stable crypto currency that has no counterparty risk.
