It has limited validity. People are way more complicated than the
simplistic "follow your own selfish egoistic interests to the letter
without taking prisoners" model of human behavior that seems
(unfortunately) so prevalent nowadays.

In the realm of pure logic, ad hominems are logically invalid,
period. However, if the question cannot be resolved by its own merits,
simple logic has little to say, and you may include additional
information in a sort-of Bayesian fashion.

Saying that a conflict of interest means that nothing this person says
makes any sense at all is in a way an admission that the subject of
discussion is not very amenable to rational argument.
