space manufactuof acrylic vs. glass?

Ummm, gold, soft and yellow,,,

The 16th century Spanish thought gold in the new world
was a great discovery. Had it stayed there it might
have been. But the recovery and transport of gold to
Spain resulted in economic collapse, as the price of
gold tumbled. Gold and other rare earths are valuable
ONLY because they are rare. Quadruple the supple and
the price drops proportionately.

Gold has few industrial applications. Most is used in
jewlery and there are only so many people to buy it.

All resource value is dependent upon rarity and the
energy to extract, refine and transport is all that
makes it costly.

In space, the energy is free. It just costs money to
convert it to an industrially useful form.

In space, all recources are free. It just takes energy
to get to them.

The energy investment to produce, transport etc is the
sole basis for cost/value and should be the basis of
any economy.

,,,it ALL comes back to energy,,,and the knowledge to
use it.
