Your proposals are the kind of strawman utilitarianism that turns out to be both wrong and stupid, for several reasons.
Also, I don't think you understand what the SIAI argues about what an unFriendly intelligence would do if programmed to maximize, say, the personal wealth of its programmers. Short story, this would be suicide or worse in terms of what the programmers would actually want. The point at which smarter-than-human AI could be successfully abused by a selfish few is after the problem of Friendliness has been solved, rather than before.
Ah, another point about maximising. What if the AI uses CEV of the programmers or the corporation? In other words, it's programmed to maximise their wealth in a way they would actually want? Solving that problem is a subset of Friendliness.
Here's why I'm not going to give money to the SIAI any time soon.
Let's suppose that Friendly AI is possible. In other words, it's possible that a small subset of humans can make a superhuman AI which uses something like Coherent Extrapolated Volition to increase the happiness of humans in general (without resorting to skeevy hacks like releasing an orgasm virus).
Now, the extrapolated volition of all humans is probably a tricky thing to determine. I don't want to get sidetracked into writing about my relationship history, but sometimes I feel like it's hard to extrapolate the volition of one human.
If it's possible to make a Friendly superhuman AI that optimises CEV, then it's surely way easier to make an unFriendly superhuman AI that optimises a much simpler variable, like the share price of IBM.
Long before a Friendly AI is developed, some research team is going to be in a position to deploy an unFriendly AI that tries to maximise the personal wealth of the researchers, or the share price of the corporation that employs them, or pursues some other goal that the rest of humanity might not like.
And who's going to stop that happening? If the executives of Corporation X are in a position to unleash an AI with a monomaniacal dedication to maximising the Corp's shareholder value, it's probably illegal for them not to do just that.
If you genuinely believe that superhuman AI is possible, it seems to me that, as well as sponsoring efforts to design Friendly AI, you need to (a) lobby against AI research by any groups who aren't 100% committed to Friendly AI (pay off reactionary politicians so AI regulation becomes a campaign issue, etc.) (b) assassinate any researchers who look like they're on track to deploying an unFriendly AI, then destroy their labs and backups.
But SIAI seems to be fixated on design at the expense of the other, equally important priorities. I'm not saying I expect SIAI to pursue illegal goals openly, but there is such a thing as a false-flag operation.
While Michelle Bachmann isn't talking about how AI research is a threat to the US constitution, and Ben Goertzel remains free and alive, I can't take the SIAI seriously.
