I get what you mean, but it makes sense in context.
Immersive "Open World" Sims with ground and space exploration have a hard time tying the two together. Often they feel like two separate games, and one of them often feels like the "second class (star) citizen". Not that making them seamlessly connected actually makes the two mechanically complimentary, but separating them by a loading screen makes this dichotomy all the more obvious. Starfield was no exception.
To exacerbate this, Bethesda made its brand the "You see that mountain? You can climb it!" game makers (Which, to be honest, I think they started to lose the plot on what made their games good when they started saying this. But that's a different conversation.). So when they made their foray into space exploration, they really had no one else to blame when folks expected a similar "You see that planet? You can fly to it!" design philosophy.
Though I think it would have been overlooked if the game was... good? At the very least, if it was way less bloated with low effort copy pasted fluff content. Complaints like this only tend to become so focal when people have more disappointment to express than meaningful critique can adequately convey.
