Interesting Post.
In the Sunday Times over here in the UK There was a comment that said Gold would have to be in excess of $2000 to have the same real terms value of the $850 historical spike of a couple of decades back.
Number of bullish/scary forecasts of $1000+ put forward some more conservative bulls at $600 and a few bears suggesting a bubble, which I can't quiet subscribe to no matter how hard I try. There has been a production gap for ages tat was only covered by Bullion reserve sales, which seems now to have ceased to offer up the supply over handf it used to.
I think with Asian wealth (India, China) we have a macro cycle coming in jewelry never mind industrial use.
Plus we have potential upside spikes even if trade wars don't erupt China may lighten up on USD Gilts purchases and push money on value commodities as well as other currencies.
Interesting times especially as a South African born and bred Brit.
