You're missing the point here.
It's about losing all of your cards when you lose one. And most people aren't going to spend money ($100) on one - yet alone TWO - cards vs. the free cards they get from their banks 24/7. If I lose my Amex, I can walk into an Amex office and get a free card in under an hour. Or have it overnighted for free.

This is purely anecdotal: every time I have lost one card I have lost all of my cards (because it's when I lose my wallet or the bag my wallet is in). In this case I'd be able to go home and grab my 'originals' and use those as my backup cards.

Maybe I'm missing your point. You don't lose the ability to get a new card quickly with Coin (i.e., Coin gets stolen, cancel cards and Amex will send a new one), you just don't gain the ability to get a replacement Coin.
I fail to see how Coin is a lack of backups. If having two copies of a card isn't 'having a backup' what is?
