Heck, just the "free" energy means you can cheaply seperate raw rock
into its consitituent elements. If you use the simplest method (a
sort of overgrown mass spectrograph) you even get the elements
seperated into isotopes.

Even if you don't go that far, asteroid mining should make sapphire
(aluminum oxide), quartz (silicon dioxide), aluminum, magnesium,
titanium, nickel & iron insanely cheap. Because they'll be "waste
materials" from the mining.

So in asteroid belts, the equivalent of wallboard may be something
like a sandwich of foamed "glass" between sheets of aluminum. Strong,
light, and a good insulator.

Ok - so re-imagining the future should start with an understanding of the differences in material availability and cost in that future.

With really cheap gold I am seeing cloth of gold becoming a popular fashion statement. Nothing has the shine of real gold and it could be really cheap to make in an automated fiber facility. So cloth of gold parachute pants on dockside because... free energy.

What other kinds of materials become possible?

What won't be cheap?

Hopefully graphite.
