But you have banned most of the means of approximating the experience of living such a life, no? In a general case you wouldn't be justified in your claim (where by general case I mean the situation where I have strong doubts you know the other entity, not the case of "the" paperclipper). Do you have a proof that having a single terminal value excludes having a rich structure of instrumental values? Or does the way you experience terminal values overwhelm the way you experience instrumental values?
