This is going too far in the right direction. Sure, in hindsight, it's easy to see how disorganized the chuds were and easy to reach the conclusion that there was no possible way it could have accomplished anything significant. But it did create a chaotic situation and at least a credible pretense of popular support for Trump, all while you have Trump openly saying he wants to remain in power and while you have a bunch of high-ranking opposing politicians trapped right there in one building. If a coup is carefully building a campfire and deliberately starting it, this was something like shoving a bunch of mediocre kindling into a pile and passing the matches around. It didn't happen, but it created conditions where it could happen.
