Don't get me wrong; insulin prices are out of control, and something should be done. But these stories about people dying because they couldn't afford $300 for a vial of insulin are misinformation; and propagating them weakens the argument to get insulin prices reduced; because it gives people a factually correct way to push back against it (what with it being factually incorrect and all). Please don't spread those stories.
Side note: People will comment about how awful R/N/L are, and say you'll always feel sick, etc. I was on R/L for on the order of a decade. It's annoying because it's effectiveness curve (of the R) means you need to take it 20 minutes (give or take; it's been a while) in advance of eating.. and if you wind up not being hungry, you have to eat anyways. But they are plenty effective for controlling blood sugar.
Even then, let's say that they work, what about cases like gestational diabetes? Are you going to do gene therapy on a pregnant person to resolve diabetes that tends to normally vanish off once the baby is born? What about the impact on the baby?
