It is not even an inferior measure, because in order to calculate gdp you first need the raw number. More accurately, it is not a measure at all, but a part of a complete measure.China might never overtake the US in nominal GDP now because the US will now have perma high inflation forever ending in hyperinflation due to mega-money printing and de-dollarization until the empire collapses.
Let's say the US has grown 1% in real terms in a year, and had 4% inflation, it means that their nominal GDP number by the end of that year is now higher 5% than the last despite it not meaning anything positive and it actually being bad for the economy.
It doesn't differentiate between raising prices and actual economic output alongside many other things. I recommend everyone to stop watching over bullshit nominal GDP numbers, it is an inferior productivity indicator in around 5-10 ways.
Without paring with the inflationary data, the result is unusable.
