I think you are wrong. Especially the whole 3 million chips not being worth 3 million part cause you just lost 5 million. If you want to make such assumptions we can include a million other factors, like the big stack being nervous cause he is a favourite to win, or the small stacks being nervous to bust and therefore playing worse?

The advantage of a big stack is no one can bust you, that's a pretty huge advantage in a tourney.
