Beside the specific excuse given for Naboo, there’s more to trade than basic life sustainability - there’s still material coming in and out for all sorts of technologies. Andor recently had an entire planet get strip-mined for its core made of a crystal that was super rare everywhere else, for one. Naboo can easily need some material for hyperspace travel or whatever that doesn’t exist on site, or not in sufficient quantity.
It’s easily observed in History right here too, where most Bronze Age cultures in the Mediterrannean collapsed when trade routes for tin and copper got burned down. People survived, but civilization and writing went into a Dark Age there. And populations tanked too by half or something, so life does get impacted.
