There are multiple viewpoints for "best interest" that are sometimes in
conflict. So the problem may not be solvable at all.

Ultimately it is the "goal" of a person's genes to get themselves into the
next generation and beyond. To do so the genes build brains that have
psychological traits that--in the past--worked most of the time to get the
genes of those bodies and brains down the time stream. Of course, genes
are more remote from day to day behavior than the board of directors of a
major company is from a shipping clerk. Thus brains develop a viewpoint
which is sometimes in conflict with the "goal" of a person's genes.
As an example, consider the celibate priest. It is possible for genes for
celibate behavior to evolve as they did in bees and ants, but there is no
evidence that the close relatives of celibate priests do enough better at
reproducing to compensate for the loss of the gene copies in the
priests. Besides, priests are post agriculture which is to say way too
recent for evolution to have shaped the psychological traits behind such
(There should be a reader who can explain the psychological trait behind
There is a statement out of evolutionary theory which (paraphrased) says
that features and behavior of a species are either the result of direct
selection or side effects (spandrels) of features or behaviors that were
selected. Sometimes, such as the behavior of taking addictive drugs, it is
clear that the trait is a side effect. In the case of drug addiction, a
side effect of a brain reward system mediated by chemicals. Some plants
make chemicals with a shape close enough to mimic the effects of the
natural reward chemicals.

Ten years ago I would have agreed with you. There is a strong libertarian
outlook in me that was shaped by decades of Heinlein's influence.
But over the past ten years I have come to see "the person" as something
less than a unified whole, burdened by evolved psychological traits that
may be way out of step with reality. Gambling, drug addiction and cult
involvement, i.e., infection with a parasitic meme, are pathological states
where intervention may be justified--not simply because of the damage to
the person, but the dangers to the larger community.
We are *social* primates. Rational behavior (sanity if you will) is to a
considerable extent maintained by interactions with those "in your
tribe." That being the case, we have self-interest in keeping our
neighbors sane, and they in keeping us sane--especially since we have
mechanisms that switch on irrational behavior in response to environmental
conditions (though "irrational behavior" may be rational from a gene's
viewpoint in a hunter gatherer environment--key phrase in Google
There really isn't a simple answer.
To relate this back to the subjects of main interest here, understanding
these matters might be essential to providing the environment in which
friendly AI can be developed.
