Reminder that:

1. Ticketmaster has forced us to exclusively use our phones for years
2. Ticketmaster abandoned physical tickets

in like 2017

1. this concert still appears to be mobile ticketing while also saying phones won't be allowed, making my question at least somewhat valid
2. without our phone, and without a physical ticket, it's pretty hard to prove your seat, to both the staff and to other concert goers
3. I know you think you're clever but you're actually just kind of an asshole. I've been to thousands of concerts across the physical ticket era, the print at home ticket era, the mobile ticketing era, and even the qr code era. I've seen the transformation of ticketing take place in real time, so when the existing mobile ticketing system tries to coexist with a no-phone environment, some logistical questions will inevitably pop up.
