has anyone done a similar analysis for "pushing for world-wide safety regulations on AI research" or "spending money directly on building FAI"?

The number one point of comparison for safety regulations is the cryptography export regulations. I am pretty sceptical about something similar being attempted for machine intelligence. It is possible to imagine the export of smart robots to "bad" countries being banned - for fear that they will reverse-engineer their secrets - but not easy to imagine that anyone will bother. Machine intelligence will ultimately be more useful than cryptography was. It seems pretty difficult to imagine an effective ban. So far, I haven't seen any serious proposals to do that.

Governments seem likely to continue promoting this kind of thing, not banning it.
