It may sound odd, but you are not bolstering your argument here. The parent is arguing for a way to ensure that participation in society is not bound by one's ability arrange for unrelated physical objects other than cash and ID to participate. And that is before we even get to how much having a car and cell phone governs one's life in US. Not everyone believes it is a good societal structure.
Note that I am not arguing one way or another, but outright dismissal is not an appropriate counter argument.
Yeah, the minimum you need to participate in US society is SSN, driver’s license number, working cell phone number, credit/debit card, health insurance, car, car insurance, proof of citizenship, permanent address, internet connection and W2 or equivalent.
I’ve needed all of these sans the car to interact with just government services in my state.
