Please fix your quoting, your post is hard to read but i get it.
So basically your argument is that gold has a high price because of the mining costs, but thats a no argument.
Thats like saying I sell a rock for 20$ just because I draw a eye on it with a marker.
http://www.petrock.com/It doesnt justify the high price, it make it look more like a scam or a hype. If the only thing that gives significant value (apart from the ones you put charts with) is central bank/ commercial bank hoarding (with printed money purchases=stealing from you through inflation to hoard this crap) and the mining cost which is a no argument; then your argument sucks and makes no sense.
If apart from jewelry,electronics,dentistry, etc uses, only central bank & other institutionals hoard it with some gold bugs, it makes it look like a scam.
Why? Because they artificially pump up the price and then exit from it by duping the retail gold bugs to buy their short orders. Thats what happens 99% of the time with trading. Institutionals come in, they hype it up, and then they exit the trade by seling their overinflated instrument to newcomer retailers.
A pump & dump scam.
