an inadvertent change of utility function is extremely dangerous, because changing your utility function is of infinite negative utility by the standards of your current utility, and vice-versa.
Not true at all. A change from N_paperclips to N_paperclips + 10^-100N_staples, for instance, probably has no effect. A change to N_paperclips + .5N_staples might result in fewer paperclips, but finitely many.
