Other concepts that happen to also be termed "values", such as your ancestors' values, don't say anything more about comparative goodness of the future-configurations, and if they do, then that is also part of your values.

I'm having difficulty understanding the relevance of this sentence. It sounds like you think I'm treating "my ancestors' values" as a term in my own set of values, instead of a separate set of values that overlaps with mine in some respects.

My ancestors tried to steer their future away from economic systems that included money loaned at interest. They were unsuccessful, and that turned out to be fortunate; loaning money turned out to be economically valuable. If they had known in advance that loaning money would work out in everyone's best interest, they would have updated their values (future-configuration preferences).

Of course, you could argue that neither of us really cared about loaning at interest; what we really cared about was a higher-level goal like a healthy economy. It would be convenient if we could establish a restate our values in a well-organized hierarchy, with a node at the top that was invariant on available information. But even if that could be done, which I doubt, it would still leave a role for available information in deciding something as concrete as a preferred future-configuration.
