This is the slippery slope of censorship on display for everyone to see. What panel of certified physicians is YouTube using to identify what information is correct vs. incorrect? I'm pretty sure they don't have any doctors doing this. The ban is a political act and not a scientific one.
Misinformation is also a slippery slope though; you have to say "enough is enough" at one point because else you reach a point of no return. See also https://en.wikipedia.org/wiki/Paradox_of_tolerance (iirc that was linked to on here a while ago, I may misremember)
By extension, a system that wants the idea of free speech to stay viable needs to protect itself from ideas that bring harm to it. Maybe it can be argued that from mathematical sense there is some kind of paradox (a set of all sets that are not blah blah), but this is no contradiction for us humans. There is no mathematical beauty in submitting to a wave of harmful, malicious misinformation.
