This is true as far as it goes, but the OP seems to be talking about a mostly rational agent with some buggy preferences. And in particular it knows its preferences are buggy and in exactly what way. As I mentioned elsewhere, I would expect such an agent to self-modify to apply an internal utility tax on trades among the affected assets, or otherwise compensate for the error. Exactly how it would do this, or even whether it’s possible in a coherent way, is an interesting problem.
