Monetary-use premium? Where exactly is it used for money these days? Porcfest? A few gun shops in Arizona? A few village merchants in remote areas of Myanmar? 

I would say that right now it's "moneyness" accounts for a VERY small percent of its current demand, and it's "hoardiness" (similar to moneyness but little to do with transactional value) as well as its speculative value, is responsible for most of its non-industrial, non-convoluted-with-jewelry demand.
Does that make sense? Obviously something that is used as money is in demand to be used as money, and usually things used as money are also good for hoarding. HOWEVER - what we're seeing with gold is rather unprecedented - most of the world has completely abandoned it as a transactional currency. But much of the world still hoards it! Central banks (esp. eastern CBs), asians, libertardian American stackers, etc. The demand is not for gold as a transactional currency - demand would be much higher if that were the case - but for gold as a hunk of metal to hoard for various reasons - inflation hedge, SHTF hedge (however misguided that may be), deflationary store of value (as unsuccessful as that's been the past couple years.)

I'm not necessarily saying gold ISN'T headed for $0, but if even a small fraction of its former demand as a transactional currency were restored (in addition to retaining its value as a hunk o' hoardiness), combined with the artificial supply from the paper market collapsing (which it won't, ever) it would indeed make gold holders quite happy. It's a pipe dream, and it's not MY pipe dream, but it's one of many things that could happen, and that's why Goat has a small % of his portfolio in PMs.
