A right to death is not mutually exclusive to aiding the poor/reducing misery.
I don't understand your critique about making money at all. I broadly agree with the comment you responded to, and my motivation is purely wanting to leave life on my own terms. It seems strange to accuse the commenter of having some ulterior financial motive.
There certainly needs to be provisions preventing marginalized people from being pressured to kill themselves. But this is also not exclusive to a right to death.
