We need to act now, while there are still service providers that don't require a phone. If my bank said they wouldn't do business with me unless I used a phone and an app, I would immediately take my business and all my accounts to a different bank. Banks have no moat. You can pretty easily move accounts to a different one or to a credit union who won't abuse you.

It builds a case. You're not going to win with one clever move. We need to show that these policies systematically deprive honest customers.
