This is not a great comparison: net worth vs market value of goods over time. E.g. what if GDP was measured in decades instead of years?
It's a perfectly good comparison in fact. Let me show you how that works. Did you know, the Stratolaunch has a wingspan wider than the length of a US football field? The equivalent reply would be: geez, that's a terrible comparison, because the Stratolaunch is not a large plot of ground, they're entirely different things! GDP is obviously not inherently measured in years. GDP has no set measurement period of time. GD…
Put another way, yes Jeff Bezos could more than double the GDP of the country in question if he donated his entire net worth as someone else's income. But so could someone with a trivial sum of money (say a single U.S. dollar) by creating a series of dummy transactions with someone else where they constantly exchange the same sum of money back and forth for dummy "services." Yet at some level it seems weird to compare Jeff Bezos with this hypothetical person.
That being said, that's just an intuition. GDP is actually calculated as a dollar amount not a rate. As such I think there's still some worthwhile explanatory value in using GDP as a measure against static monetary amounts in the same way that you can say "this swimming pool has the same amount of water as the amount of water that flows over Niagara Falls in a day" (to the best of my knowledge such a large pool does not exist).
