Zoom is terrible for presence, as in feeling like both of you are in the same place which VR achieves quite easily even with terrible graphics. That is very hard to demo. You have to experience it yourself for more than one 5 minute session. I strongly doubt that you’ve even used a Quest just based on your comments. It has many problems and flaws, but “too much effort to use” isn’t one of them.
Putting something on that requires full immersion requires you to be able to fully block out time, and have physical space available, with all of the necessary equipment is effort. That physical space also needs to be a trusted space, since you're unable to know what's going on around you. For zoom, I can join on my cell phone, from basically anywhere.
