I think the first 3/4ths are very well stated. I couldn't agree more.

On the last bit, my personal intuition is there are plenty of things people can do for FAI research beyond raising money. Moreover, such intangibles are likely often more important to the cause of FAI than cash.

(Also, the argument that "some of those willing and able able to do FAI research are spending their time raising money, right now, for lack of other ways to get money" may be undermined by the paragraph above it; e.g., I'd rather be thinking about FAI than raising money for others to think about FAI.)
