You are right, they could store their actual wallet addresses on their phone. But would that actually be a good idea? I would sure hate to loose all my money because it rained hard while walking home. And all the other dangers that haunt phones. A counter here of they should be backing up is unacceptable. Many people who are otherwise very knowledgeable don't make backups. Sure, if they have all their money under a mattress then they are venerable to house fire, theft, and the like. But storing all their money on a cheaply made but affordable electronic device has the same problems, while opening up a ton more possibilities of chronic money loss.
