I think you may be right about every click bringing more frustration - and a more likely bounce.
But I don't think your assumption that Google uses bounce rate as a ranking metric is accurate. That's what several members here have conjectured, but several Google spokespeople have repeatedly said that the basic bounce rate is too noisy a metric for the algorithm to use.
If there's anything close to bounce rate in the algo, it's some combination of bounce rate and time on page (dwell time). In fact, the Google Analytics blog just published an article about how to get an adjusted bounce rate, where a time-on-page over so many seconds (your choice on how many) means that a bounce is no longer counted as a bounce!
