Can we design an affordable 3D printed self sufficient housing option?

If we could design the "cell" (which would be completely self sufficient) to enable connection to other cells with ease we could design bigger community spaces as, where, and when required.

We could design the cells to have wheels, sail in the sea, fly, or even magnetically levitate and go in to space!

Imagine having everything you need and work for right now, created with ease for the rest of your life.

Can this happen? Or Am I just crazy?
