That's false as moving away from your ship a certain distance (I think 6 or 7 km), it'll literally tell you you've reached the boundary of the area and you need to land somewhere else to get a new stretch of land.

No! That's impossible! I was told by people who played less than an hour if at all that you simply can't walk or fly anywhere and MUST fast travel everywhere.

This particular point really annoys me, I'd love to have somewhere that actually feels remote, where I don't have four more copies of the same mining and science outposts in visual range. No matter how large humanity has become it just doesn't make any sense that you can't find a single ~15km square without anything man made on it.

The best remote places I've found so far has been in some quest-specific areas, but even then there's usually a facility somewhere within a kilometer of the quest location.
