I may be in the minority here, but I do, and frequently have. There is a sizeable community like that, but we don't seem to really fall into Apple's target market, and it will be interesting to see how orthogonal that willingness is to being a techie shut-in.

For me, the big reason I don't wear it 8-10 hours per day when I'm working like I do when I'm playing is the pixel density. Current VR headsets (except maybe Varjo's) don't do a good job of simulating even one 4k screen, let alone competing with a multi-monitor setup, so they fall short for productivity. Once that's solved (and that's the claim Apple seems to be making here), the case for use as a primary work machine is very compelling. It lets you set up something like this for the cost of a headset and a reclining office chair, and is also somehow portable.

It fails if you use it exactly like you use a laptop, just like a phone does. If you take advantage of the increased flexibility though, it has pretty transformative potential.

That said, that's the perspective of a technologist with no kids who works from home. I wouldn't buy this because its standout features are irrelevant to me, so I'm from a representative sample of the market they're chasing.
