I think you are casually forgetting all the times that the Biden administration tried to pass good stuff and it was blocked by the GOP ‘just because’ or SCOTUS because they are captured by the Sith.
Cheaper to get, bulks it out, flavours it more efficiently? Any number of reason.
There was that apple sauce scandal in the US recently where kids were getting chunky doses of lead because waaaaaaaay down the production chain, some dude grinding cinnamon in Ecuador chose to bulk out his milling output with lead chromate (for the red-orange colour pop) amongst other powders which were not cinnamon.
More government testing up and down the production chain could help stop that sort of thing. Hopefully dodgy imports avoiding the tests at one level, would get clamped at another.
I love the theory, but considering that every week we see some headline about some digital fraud or another, I think there is a great reassurance in keeping democracy as analogue as possible
