Granted, and as we have seen with the MCX member merchants (CVS, et al) it can be disabled. But as far as merchants who have no "dog in the fight" and simply don't accept NFC payments today because they lack the equipment (which is the vast majority of merchants out there), we can expect wider adoption in 2015. I expect that some of the MCX merchants may join Meijer and defect from MCX... But we will see.
I'm already noting a number of small businesses near me that are now accepting NFC payments.
Incidentally, the whole "we can't track you" argument, to me, is largely baseless. Merchants shouldn't be tracking you via credit card number - storing it obviously leads to problems, and certainly shouldn't use it as the sole identifier (since they can't perform demographic analysis, for one). I think Walgreens has the best approach for today - you can use Passbook to scan your loyalty card (which obviously permits them to track you), and then pay with Apple Pay. Takes even less time for me than to either pull both a Walgreens card AND a credit card out of my wallet and use both OR to use Passbook and then dig for a credit card. Scan barcode, tap, done. Many other merchants could do the same thing; and for many, it would simply be a matter of supporting Passbook. Heck, Starbucks - who apparently isn't enamored of Apple Pay (though they are apparently rolling out NFC and support for it) already allows you to store your card in Passbook; if they were to convert it to a straight loyalty card and remove the payment feature, it'd be pretty much a done deal.
Of course, when you re-load your Starbucks card, you are guaranteeing them future business, which can be seductive to them as well... But since they will be permitting Apple Pay in-app to do it... Well, the arguments start to unravel a bit.
