Honestly, I believe it's very intentional. The idea is this device will be personal, like a phone or watch. Not a device you'll park in dock at home. If you have a family, they'll all need their own headset.
I also believe it's intentional, and it fits very well with the dystopian marketing towards young singles and divorced dads. However, this alone would be a showstopper for me. The idea to buy a 3.5k$ device, which is ideal for watching media, and not being able to lend it to my wife or kids, is just ridiculous.
