Sure. It's worth some as an industrial metal. Doesn't corode and it can be spread very thin. Industry needs very little of it tho. If it wasn't for jewelry and for some reason currency proxy, you probably couldn't give it away. Too soft to be of much use...
Sure. It's a metal with meaningful industrial uses, so it has an actual value outside of "hedging against reality". Since that value is very low relative to its trading value, it means Gold is by definition in a bubble state.
The reason that the Fed is depressing the gold price is because of a discovery by Larry Summars and Robert Rubin that as long as gold price is under control printing of usd will not cause inflation. I do not understand the connection between gold price and inflation honestly. I have been trying to locate the paper.
I just like the way the sparkly gold looks when it is worn by my lovely wife. If it costs me less to buy it tomorrow than it did today I will just smile and buy more.
