To me, it starts to feel like work when I have to rebuild large parts of my factory because I didn't leave enough space to expand. This process feels exactly like having to refactor a bad codebase (where you feel the urge to just start from scratch).
If you plan your build properly, you can avoid this, but it takes a few runs to learn the best strategies.
