He's including the value of what happened as part of what makes it a miracle. Blind people being able to see, the hungry becoming fed, all of these are pretty much purely benevolently "good", and hence miracles.

Your example of something miraculous is something that most people would view as having a selfish motive, and doesn't count as a "miracle". Along the same lines of thought would be saying...having a meteor specifically strike a metropolitan city each day would have similar rarity, but people'd be saying it's the apocalypse before they called it miraculous.
