SPY when priced in Gold very close to ATH

I've been pricing everything I look at in Gold lately. Since you don't want to hold USD, it doesn't make sense to denominate things in USD. The inflationary nature of USD screws everything up in regards to purchasing power, so I have been pricing everything I look at in Gold and see very different charts.
