> not use a smartphone, or any phone at all.

There are some real-world issues with that, all of which a friend recently encountered (they don't even use a credit card). Firstly, if you don't set up internet/mobile banking, it does leave you open to someone doing it "for you." Luckily money in the bank is insured, but that doesn't help the stress experienced by a 70 y/o (who was doing all the right stuff, as she's retired intelligence). Secondly, you're going to struggle if you're forced into some situation away from your landline, such as a hospital visit.

I was able to repurpose my Pixel 4 with GrapheneOS for her: no app store, no email, no scrolly things, data disabled, no e-waste, nothing but phone calls over LTE.
