Phones break and get lost/stolen.

All of us--and I include myself although I try to have some backup information on paper--have probably become too dependent on a single physical device which sucks in more and more information every year. See ongoing digitization of driver's licenses.

Especially for international travel, but really generally, I try to make it so I'm not completely screwed if something were to happen to my phone.

I try to still print out boarding passes when I can cos I don't want to deal with delays or missing a flight if my phone runs out of battery, especially if it's a flight out after a full day out and about. It's also less annoying at the airport fiddling with my phone to get the right barcode up each time it's needed (and no, I won't put it in to Google wallet)

I don't go out of way to print boarding passes when I'm on the road. But certainly at home, it takes maybe a minute so why not?

I stopped doing this when I realized I hadn't used a single paper one in about 50 flights.

You'll start doing it again after someone swipes your phone at the airport (yes, this still happens) and you miss your plane waiting in line to deal with the customer service agents.

I guess that depends on airport. Typically I could get a paper one printed at kiosk using ID if needed, usually 10 min or less. One of the reasons I stopped bothering.

Same. Paper has no downtime.

Yes, the "one device per phone number" restriction is quite annoying. I'd like to have multiple, functional copies of my phone. Instead I settle for a phone and a 4G watch, paying for one phone number for each. Since eSIM providers allow cloning but I haven't tried that yet.
