It isn't that near Spawn and Drew actually specifically found an area that was away from things with suitable amounts of flat area for when him, Patch and Kev started work on the Citadel. It may look like it's near everything now but it didn't used to be, buildings have sprung up nearby.
Yeah it's difficult to know who is using what area but surely people want their own space for expansion etc so why not have a wander elsewhere. The map is there for a reason so you can see what's about, where's flat, where the water is, you can see the railway on it to see how easy it is to get to.
If you feel out of the way build a railway and ask Kev nicely to connect it to the mainline and he'll do the job.
