Choosing a Tin Can for a child that doesn't have a phone isn't restricting them, it's empowering them with a new form of communication to chat to their friends. Getting my 10 year old a bicycle instead of a car isn't a restriction.

Compared to getting them nothing, yes. But the OP's point is that this doesn't prevent the child from mentally comparing themselves to peers that have a smartphone, and viewing their Tin Can as a "restriction" imposed by their parents.

Which it is. I don't understand the need to wink-wink-nudge-nudge pretend it's anything else by the others in this thread. Just own it, restrictions aren't bad by default.
