Unless you were Steve Jobs in late 90s Apple, when in fact they did have to throw all the source away, start over with a new stack and new devs, with imported ideas, not exactly knowing what the outcome would be like. Then you wouldn't be a moron, you'd be hailed as a business genius (I mean NeXTStep->macOS).
US healthcare is broken. Most attempts to fix it make it worse because they don't address the root causes. That doesn't mean everyone who points it out needs to present a 300 page plan for how to address it.
So other than Jobs having a plan, having a proven dev culture that he himself built up, having a production OS, he had nothing?
Not everyone needs to have a 300 page plan, but the Steve Jobs/Politicians pushing to blow things up need to. Or in Job's case he started with way, way, more than just a 300 page plan.
