God, I keep seeing this buffoonish comment from shitcoiners over and over.  It doesn't matter if it's technically possible, all that matters is cost of production per ounce.  Nobody is going to mine gold in space for a million dollars or more an ounce.  They would mine on the ocean floor or somewhere first.  You might as well make the statement "someday it's inevitable humans will build a Dyson Sphere around the sun".
