I agree with you about how awesome Jacob Appelbaum makes Tor sound, but you could still make a case about not wanting your computer to be used without your consent for stuff like that.
For example, as much as cancer research can benefit from extra computing power, I wouldn't want web sites to start including secret javascript code meant to "reap the spare cpu cycles" available when I visit their site.
