Thats a good point. In many cases the constraints of designing UI for consoles can lead to better, more refined interfaces. But the constraints are real, and it's not necessarily all having to do with the general public being "dumb". There is an issue of resolution. There is the fact that console players are generally going to be much further away from the screen. And there's the interface itself; everything has to work pretty OK with a gamepad.
So you get icons. You get giant pop-up windows and oversized text highlighted in different colors. And you can't rely on fine details to convey meaningful information the way you can on a PC screen. The metaphor for graphic design on PC is like a page in a book. For consoles it's something closer to a poster on a wall. There are some strategies which work well with both, but most solutions work way better in one than the other and some are absolutely mutually exclusive.
None of this excuses Frontier's GUI spam, though it doesn't seem unreasonable to suggest that some of these bad decisions were the result of Frontier TRYING to optimize their game towards consoles.

I would just like to point out that consoles have better resolution than VR, and a lot of PC gamers actually prefer using an XBox or Playstation controller to play ED. In fact I would argue that my DS4 is superior for navigating a UI (and galaxy map) compared to the average HOTAS. And I personally would not want a UI optimized for K&M, since flying a spaceship with a mouse is, as Scotty said, "How quaint."
Oh, and on the matter of font sizes and such, I would want my ED systems to follow the Human Interface Guidelines for UIs in say, automobiles, not for a word processor on a PC. I have a feeling the screen in a Tesla isn't using tiny fonts and icons.
