Gotta disagree with you on this one, since in your example, 'candies' corresponds with USD in the real situation, while USD corresponds with ETH, which is quite distinctly not a real currency.
I was considering ETH to be a commodity like candies. That might not be technically a fair comparison. Replace candies with another currency. GBP or Euro.
If you were considering ETH a commodity like candies then in your example the person would've been paid $1000 back, which was the currency, in which case there's no point to the comparison.
