Fair enough, but in that example making irreversible decisions is unavoidable. What if we consider a modified tree such that one and only one branch is traversible in both directions, and utility can be anywhere?
I expect we get that the reversible brach is the most popular across the distribution of utility functions (but not necessarily that most utility functions prefer it). That sounds like cause for optimism—‘optimal policies tend to avoid irreversible changes’.
