Far too much of the modern world including our societal systems require a smartphone. Wether its a QR code showing COVID vax status, checking email, engaging with your local bank via the app, connecting with friends, etc.
We have built a world that is so reliant on the apps ecosystem (at least in the US) so it's unhelpful to say "flip phone can get text messages".
I don't really disagree that we're moving to a place where a smartphone is universally needed because of apps but I'm not sure we're universally there today.
So no, it’s not food and water level necessary but it’s pretty damn important.
A smartphone just happens to be the easiest way to get phone/SMS & internet. As noted elsewhere, a massive number of Americans (and people worldwide) use their phone as their only means of internet access.
OK so you need a printer, ink, probably a PC… (Or at least access to one, which would be a fine requirement, if the US had good public transport and libraries...)
I won't disagree that these things are massively inconvenient compared to doing it all though a smartphone, but it's far from impossible.
And for what? Understanding and accessing government services, particularly for those trying to escape homelessness. Most of this is done online. The only other realistic option is a public library, but the hours are limited, and they’re geographically inaccessible to lots of folks.
I suppose it didn't need to be an activated phone though. You could probably get buy with cheap android phone you buy at CVS and use the school's wifi.
