It's all well and good to say that your chosen priest caste won't exert hierarchical control, pinky swear, but history and human nature disagrees with you.
It's also odd to suggest that we can teach a system of deriving ethics or morality. Philosophers have been hard at work on this for a long time and haven't gotten terribly far, and they disagree with each other quite strenuously.
They teach the different ethical frameworks, where they come from, and then get you to apply them to different situations. The classes don't tell you what's right and what's wrong, but rather, the different frameworks people can use to determine that.
That said, who did SBF largely derive his ethics from? His parents, at home, not at his mom's lectures. So all this does is illuminate why it's important for people to get exposed to a wider variety of opinions and ethical considerations.
In any event, the poster I replied to also included "morality" alongside "ethics", which is why I suggest it's not as cut and dried as you imply.
Parents can teach right and wrong, but they seldom teach about things like utilitarianism or hedonic treadmills.
I assume you've lived long enough to witness an internet stewarded by those who place ethics or morality above purely capitalistic motivation, vs. an internet stewarded by a generation of new-age, fake-ethical "They 'trust me'. Dumb fucks" tech entrepreneurs.
