At some point the game itself (hence, the devs) does encourage you to exploit more verticallity, and the buildings are certainly designed to be huge. This may be an extreme case as presented here, but even for "realistic" late-game multi-story factories, jump pads don't quite cut it.
A good example is getting to the crystal mines above the grasslands; I have about 70 stacked containers (probably fastest way to build ladders) and a long climb time to do so. Equivalently you can make 10 jump pads. It would be far more practical, and aesthetically pleasing to have a proper elevator.
As it stands, you have the ability to climb to infinite heights as soon as you're past the early game and have large amounts of plates and rods available; giving a faster (likely more expensive) option takes nothing away from the map but does give us the option to make our gaming experience less tedious.
Besides... jump pads? Seriously?
