I'm fairly sure this comment was not exactly intended as a compliment, but I can think of worse insults than having my writing put in the same category as Nick Bostrom. As the author of the first of these parables, even I recognize that these two stories differ very significantly in quality

The Blue and Green Martians parable was an attempt to discuss a question of ethics that is important to many members of this community, and which it is almost impossible to discuss elsewhere. The decision to use an analogy was an attempt to minimize mindkill. This did not succeed. However, I am fairly sure that if I had chosen *not* to use an analogy, the resulting flamewar would have been immense. This probably means that there are certain topics we just can't discuss, which feels distinctly suboptimal, but I'm not sure I have a better solution.

I don't understand what you mean by "utility bound". A bounded utility function is just a function which takes values in a finite interval.

Let me try rephrasing this a bit.

What if, depending on other circumstances(say the flip of a fair coin), your utility function can take values in either a finite(if heads) or infinite(if tails) interval?

Would that entire situation be bounded, unbounded, neither, or is my previous question ill posed?
