It's not apparent from the UNHDR alone that it shouldn't be honoured. It would hinge on "the innate human desire to treat the wishes of once-living persons with respect.".
It would fall to you to demonstrate why "you don't get to put your works under perpetual copyright.".
Your post holds such an argument "regardless of whether the use shows any respect for the author's work.". Surely holding the copyright, means treating the "wishes of once-living persons with respect" not just respecitng the income. One wonders if copyright holders could be sued for not treating the wishes of once-living persons with respect?
