1. You could make the same argument about fridges, electricity, light bulbs, vehicles (yours or by proxy), houses, chairs, agriculture. The point is that not having a smartphone available to you puts you on the margins since at this point it's assumed that everyone has one. Every restaurant in our area is now doing virtual no-touch menus that require scanning a QR code and requiring online ordering for take-out. Like you can live without a smartphone but at this point you're only making life more difficult and annoying for yourself.
2. It's plenty enough. Phones have been plenty fast for years. The issue is finding a vendor that will support your software for long stretches of time which right now that is community Android distributions and Apple.
I don't think he's wrong. Society has expectations and throwing money to buy things works. I don't have Uber and Lyft and that puts me at margins with society. Does that mean they're essential apps? Making life difficult and annoying is just how many people without money live.

3. This is a bad-faith argument and you know it.
