Because focussing on an enthusiast market is a bad business practice since they generally have little brand loyalty and will go for whatever is the best solution in their price bracket. Competing in such an environment is a big business risk since you need to stay on the top for R&D to be succesful. Not to mention the inherent costs makes PCVR a luxury product, blocking a lot of consumers from getting it.

Making a new market out of normies is a lot easier however, especially since they're the only company making such a normie friendly experience. Add to that that it's relatively inexpensive and you can have everything you need for the price of a games console, making it more accessible. They might as well just keep going while they have the lead in that market, just look at how well the Quest has been selling. 

That said, as an enthusiast the above is really dissapointing. I hope that the Quest 2 has more thought into being used as a PC headset as well as standalone, on the Quest it felt like it was mostly tacked on.
