Well, that's what kills it for me in the first place.
Fast travel makes the game not representing a full world (or a 1000 worlds as they claim), but a library with 1000 drawers - sure i can put my imagination at work, but yea it's not the same thing.
Edit: for me the best Bethesda game was Morrowind - so i dont really need huge spaces to be able to immensely enjoy a game
But for Starfield, they really overhyped the scale, sometimes in an extremely inaccurate way (see the remark from the head of publishing regarding full planetary exploration), only to find out that SF is basically a collection of "rooms" separated by loading screens
