Your train of replies reminds me of a canard I saw once on Twitter, can't remember by who: "Everything is monocausal and the cause the the thing I care most about." Your thing is regulation, apparently.
Regulation affects everybody a great deal, whether you're aware of it or not. In this case, insulin regulation has created a single supplier and prevented the market from working.
You seem to treat “regulation” as if it is some monolithic and controllable thing where the president could have a dial installed to their desk to turn it up and down.
