I don't doubt that your experience is valid, but it's not everyone's. For instance, I use the old busted Quest 2 headset every single day, and I don't get any nausea, or neck soreness. (I do definitely get the sweaty head, though. Largely because I use a boxing exercise app with it, which gets really sweaty, but in non-exertion use cases, too. (I also tend to sweat in hats and over-ear headphones.) The sweat problem will gradually get better over time, as headsets get lighter and more breathable. Unlike a lot of VR enthusiasts, though, my own interest is almost exlcusively in replicated an expansive, multi-monitor setup for sofware engineering. Why? I have an XXL desk from GeekDesk with 3 large high-res monitors. It's fantastically productive. So much so that it makes working on a laptop, or even a desktop with only 1 monitor, super annoying. But I want to be able to take that workspace with me. (Even to work; I work at home mainly and when I do go into the office and get stuck with a single busted-ass low-res 4K display, it sucks. But I want to take my workspace other places, too.) I'll put up with some minor annoyances, like sweat, to be able to do that. In your case, it sounds like they will need to solve more problems to make it usable — or you might just decide to stick with a real desk and monitors, and that portability isn't worth the tradeoffs.
