This. If, somehow, an alternative currency were to suddenly, be accessible anywhere with Square (just as an example of some single vendor that could make altcoins usable at thousands of vendors), it'd be a major reason for people to choose that currency over Bitcoin. It would mean you could buy lunch at a couple dozen places in your home town, pay for services, go see a show, etc. all with your altcoin. Square isn't used in a high percentage of places, but it's in use at a lot more places than Bitcoin. If they transparently added some sort of alternative currency support, it would change the landscape.
