I think 1-4 are good summaries of the arguments I'm making about nanobots. I would add another point that the reason it is hard to make nanobots is not about a lack of computational abilities (although that could also be a bottleneck) but simply a lack of knowledge about the physical world that can only be resolved by learning more about the physical world in a way that is relevant to making nanobots.
On point 5, from my current perspective, I think the idea of pivotal acts is totalitarian, not a good idea and most likely to screw things up if ever attempte...
