Power-seeking and Status-seeking : Different from Profit-Seeking?

I just read Randall Holcombe's "Government: Unnecessary, but Inevitable," and he addresses a point in libertarian anarcho-capitalism that I have been thinking about for some time. Specifically, he notes that profit-seeking protection agencies have an incentive to become predatory in addition to being protective, to establish monopolies (denying people the market opportunity to choose among them) because monopolies earn above-market profits.

But there is another issue that I have not seen addressed in this literature (although I am not fully versed in it yet, so I may just be overlooking it), which is that profits - in the sense of financial gains - are means to an end. We give up money for things we value more, not simply in spending money we already have, but in foregoing financial gains in favour of other things we value (more leisure time, a less stressful career track, etc.).

My general take is that even below-market gains would tempt those whose motivation is power. Mancur Olson suggested that dictators - at least given an effective time horizon - would want to increase the productivity of their country, to increase their own returns. But if power is one's motivation, and concern for relative rather than absolute status (which I suspect is characteristic of power seekers) that's not necessarily the case, if those productivity gains limit the absolute power and relative status of the dictator. Well-off people have a proclivity towards demanding liberty, and often more effective means of achieving it (even if that simply means fleeing the country with their wealth).
