Zero reason to set it against an ounce, for example the British sovereign was more like a quarter ounce and that was set as the standard unit or base amount of pricing for GBP. Obviously that coin is now no longer standard, the base unit of UK is tiny. So its now priced at 254 GBP or over 300 dollars, that represents the depreciation in UK currency over a century. it's all nonsensical anyway. parity is just a psychological idea---it doesn't hold any actual significance outside of perception. it's even sillier to compare the price of assets that can't be measured against one another. it's not like we can measure bitcoins in weight.
I'm going to dig up this video I mentioned as everyone should watch it and mull over possible future moves on dollar. Its going to effect us all, these trillions built up in debt will be dispersed somehow (consider how likely government runs trillions in surplus to repay debt) and not likely to common mans advantage. Japan has been doing QE programs since the 90's so some think it'll just continue forever but I doubt it Anyway he does do some solid maths behind that 10k estimate which is the surprising bit I agree, that it can be estimated at all
Heres the info and video as mentioned:
