You say "most" people have devices and that's true.

But tech ages and all of those devices will be replaced at some point. And as far as that goes, all of those existing devices are at different stages in that cycle.

I might not be ready to replace my new 16" MBP and Studio Display today, but you (for example) may well have been considering replacing that aging 2013 MBP and Cinema Display.

Now it may be that Vision Pro doesn't have what it takes to replace that setup. But if it did?

Or what if it let you get all of that gear off that crowded desk or table in the living room and make better use of that space?

Just food for thought.
