There’s your problem. We don’t say that two things are the same if they happen to coincide under exceptional circumstances, we say they are the same if they coincide under every possible circumstance.
Ethical utilitarianism and utility based decision theory don’t coincide when someone is only a little more altruistic than a sociopath. Utilitarianism is notorious for being very demanding, so having a personal UF that coincides with the aggregate used by utilitarianism requires Ghandi level altruism., and is therefore improbable.
Likewise, decision theory can imply a CC equilibrium, but does not do so in every case.
