This picture is misleading, gold prices in 1933 cost around $500 USD (adjusted for inflation). The image suggests that each dollar in the 2 stacks has the same value, when in reality, the right stack is 1933 US dollars, and the left stack is 2020 US dollars.
The correct comparison would have been to have a stack of ~500USD on the right side, but that doesn't convey the pro-gold dogma as clearly.
Also:

We can pick dates as arbitrarily as we like. How small would my money stack be today, compared to 1980? Less than 15% the height of the 1980 stack.
