Strawman, but you raise a good point. Credit card terminals can still work in certain disaster situations more reliably than trying to get everyone to not lose their phones and keeping them charged and wasting precious energy on a transaction. A credit card doesn't require electricity, and even the classical process of carbon copying can work without power or internet to the pos (though that has its own problems - but we're talking "disasters") Regardless, a person not having a smart phone should not be grounds of exclusion from society. It's too vulnerable of a device for it to be a single point of failure. It already is too critical of a device even for those that have one, that losing it is already a very big burden. Even just switching to a new phone via the migration process on Android can still be a burden.
