Asteroid -- gold melts at a low temperate relatively. Any gold incoming would be dispersed widely, most of the world is water and its already true that the oceans contain giant reserves of gold however its very hard to get at and collect.
I wouldn't call a thousand degrees Celsius a low temperature, it's well above other metals like lead copper zinc or aluminum.
Besides gold is heavy, an insane density that would make fragmentation and spreading across huge distances not likely.
Nuclear - sure its possible, I won't discount genius but today its not a reasonable way

I'm not a gold bug, gold has no yield and good business will always be worth more, grow more and be more profitable but the world needs to have a way to store value. Ironically gold is useful for not being used in industry as much as oil or alternate standards to back a nations money
That's because you can use gold in different things and you can recycle them and get back the gold.
From jewelry to computers parts, you can reclaim the gold, with oil...once you burn it ..it's gone
