That's totally cool. We're all entitled to like and value different things. The awesome thing with video games is that because there are so many of them, one can pick from a spectrum of realism. It's not an all-or-nothing problem.
There are a ton of people who value photorealism, and that's why resources are being put into it. And it's certainly not seen as "wastefulness" by those people. Personally, I would absolutely love to be able to put on a pair of VR goggles and be unable to tell if I'm viewing a real-time render, or a remote stereoscopic camera feed of a real scene. Yet, I don't think that fantastical physically-unrealistic rendering is a "wasteful" use of resources.
If we were discussing a video game, I'd agree, but we're discussing a tool for creating video games. A tool that influences creators' understanding of what they can make. If the tool becomes opinionated, it will produce works accordingly. When Unity makes hyperrealistic humans easy to make, that's what we'll be seeing people make with it.
