- total payments to the federal government exceed total receipts from the federal government
- has a coastline which facilitates foreign trade
- has an economy variously ranked as the 7th to 10th largest in the world; Spain, Canada, Brazil, Russia, and India survive with smaller economies
Even your strongest argument does not work. Who holds the trade agreements that benefit the ports of California? The federal government does. Who buys that vast majority of the products imported into California through those ports? The other states of the union do...that is who. Who buys the oil that comes out of California? The federal government does. Where does California get it's natural gas from? Other states of the union. Where does the majority of California's power come from? From that natural gas it receives from outside the state. And so on and so on...
You need to think through your assertions a bit more thoroughly next time.
