We could use hemp and dead wood to 3d print basic furnitures.

Utilities? U mean water and electricity? That can be captured from rain and from sun. Carbon from the atmosphere can be used to build diamondoid materials and nanotubes. Allowing for structures 100x stronger than steel. Nanostructured carbon is believed may be strong enough to build a cable into space.

Similar use of cheap ubiquitous minerals allow for creation of electronics, antennas, filters, insulation once they are nanostructured.

A day will come when the infrastructure itself is alive and the buildings grow and repair themselves according to designs.

Shortly after agi asi is likely and shortly after asi mastery of nanotechnology. Nanomachines allow for human equivalent droid creation. But also the structures themselves can grow change repair and clean as needed.
