Yes but
"Any individual incurs costs by protesting - at the very least losses of time and money, and in more extreme cases imprisonment and death"

This assumes that people protest purely out of self-interest rather than for a common (altruistic) purpose and that personal cost is irrational

"Any individual's protest makes very little difference"

Yes of course, but protesting is about numbers. It's as a collective that the difference is made.

"If the protest *is* effective, non-participants gain the same benefits as participants"

Of course, but unless you're approaching this from the belief that protest is purely motivated by self-interest ("Why should other people benefit from my efforts") then this doesn't matter, and is surely a desired result.

Those with the least to least lose generally protest because they have the most to gain.

To restate the point above
I'm not saying protest is impossible - obviously it happens. My point is that because it *does* fly in the face of any self-interested analysis, it takes exceptional circumstances to make most people do it. We grumble and moan, but most of us don't participate in any direct action. The job for anyone trying to raise support for a cause is to find ways to persuade people that it is worth devoting time, effort and potential loss of life and liberty for. I don't think that's a particularly exceptionable thing to point out - what's nice about the book is that by framing the problem in terms of rational actor theory it becomes easier to study - as with the better-known Prisoner's Dilemma.

Regarding 'Those with the least to least lose generally protest because they have the most to gain', I'm not sure that's borne out by the facts. Students generally don't have much more reason to protest than others, but they're much more willing to do it. Conversely it's quite hard to get poor people in low-paid jobs to protest because they're more concerned about their loss of income.

And to see examples of all these arguments, you only have to look at some of the answers on this qotw
