> The Apple Vision Pro has VR and AR capabilities. When you view a representation of your monitor it's VR. When your monitor is represented as an object in physical space then it's AR. Apple Vision Pro can do both, but my point is I don't understand the value in the latter, at least at the price point

Safety is a big reason to prefer AR for "big monitors" in HMD, especially in any home with furniture (much less clutter) or children or pets. Apple's argument so far seems to be that to get that sort of AR right in an HMD form factor much of the price is necessary (they pack in a lot of cameras to do it right) and the high price may not be an accident, it may be a requirement for good AR (at least in an HMD with current tech).
