If you have a bit of life experience, you’ll see that it often takes a disproportional amount of political effort to get people that are stubbornly doing the wrong thing to change their minds. Most of the time, you would get much more done by just doing it yourself instead of spending months trying to get someone else to do it, or at least to stop blocking you from doing it, then to stop undoing your work the moment they let you do it correctly. You know that you’re in a problematic environment when nothing ever gets done unless the people in supervisory roles aren’t looking and know nothing about what you’re doing.
Also, you really can’t go into a project wanting to tear the whole thing down when no one else shares your opinion. That’s a recipe for disaster for all involved. It will turn toxic. Fast. The only time that’s feasible is when you have the power to boot anyone that disagrees with you. You will have to be a dictator to make it work.
