I mean, as an exercise in what we could do after, sure, I suppose that works. Brainstorming is nice.... If that is what you are after.
But, honestly, I don't really think that approach works particularly well. If the problems we faced were merely complicated, such that someone could reasonably answer a question like "what should they do after they occupy the buildings?", then I strongly suspect that we would have already solved it. So, the fact that these problems persist suggests that approach won't work; it suggests complexity rather than complication. Which means that solving them isn't so much a matter of planning two or more steps ahead, but, instead, action, consequence, and reaction. We need to take actions that might have an effect, see what effect they have, and iterate, preferably as quickly as possible as our enemies are trying to do the same.
Moreover, I have an issue with "since he suggested the idea", it feels loaded. And I'm not sure it's loaded in a productive way. It feels like it implies that, unless you can answer questions like "what will fix the problem", then your suggestion might lack merit. But, of course, if we are dealing with a problem which is both too big for any one person to solve and also within the complex domain, well, that's a strategy for failure: complex things tend to be too unpredictable for such questions to work.
All that said, I would also suggest we consider organization. The reality is that, historiclly, the solutions to these kinds of situations pretty much always came as a result of alternative power structures. Some organized structure that people can follow instead of doing what Trump (or the Congressional Democratic Leaership) suggests. That happens because you are organized. Collective responsibility is about lifting together, that can only happen when we lift in the same direction. And I would argue that we are severely lacking in such capibility.
