You're 100% right here, but you're kinda missing the point. We're not really talking about sharing communal things. We're talking about forcing kids to share something that is specifically theirs. That's a little different. I'm not saying you shouldn't push sharing even in that case, but IMO you have to be careful about doing that for the reasons that @DOS_patos mentioned.
The thing is tho with big stuff like computers game systems music systems(radios and shit) most folks aren’t gonna buy multiple versions of those things for each kid. Stuff like that is usually shared and no mom is gonna let one play PlayStation and the other don’t get to play
