FYI I think your first skepticism was mentioned in the safety from speed section; she concludes that section:
These [objections] all seem plausible. But also plausibly wrong. I don’t know of a decisive analysis of any of these considerations, and am not going to do one here. My impression is that they could basically all go either way.
She mentions your second skepticism near the top, but I don’t see anywhere she directly addresses it.

Thanks, that’s good to know.
