Gold is a worse conductor than copper. The benefit is just protection from corrosion.
(Copper conductivity is 6 * 10^7 S/m, gold is 4*10^7 S/m. Silver is 6.3 * 10^7, but very prone to corrosion).

Human self-sufficiency in space— what’s needed for any real redundancy-- is for sure >50 and probably >250 years away.
Space settlements are going to need support from Earth for the conceivable future.
Even a destroyed planet from global warming or the middle of the ocean is infinitely more hospitable than the space environment.
