I can see both sides. Most people only connect their projects to a rail once it's complete - or at least releasable. I know that's my plan with my house. Until that time, one can /home to get there. With my latest expansion, it does take a little bit of time to walk back and forth from where I'm working to where I can dump off resources, but I accept that as part of the game. My case isn't that bad, though - perhaps a minute to walk back & forth. I can imagine other, larger projects taking far longer to traverse...
I think an ideal compromise would be to allow each player either 2 /home's, or one /home, and one private warp point. That would reduce most of the warp point proliferation, while still allowing people with large projects a way to cut down the travel time. I don't know if such a thing is possible for sure, but I thought I saw something like "You have created 1 warp point out of [unlimited] allowed" when I made my private "/warp home" point...
