>Aka, remove Section 230. If the platform was to be charged for posting dangerous content, the platform would magically be able to largely prevent it overnight.
That's not actually what Section 230 does. It prevents the platform from being charged if while moderating it makes a mistake.
Removing Section 230 would do more harm than good if you consider censorship good- because then the only option to escape legal liability would be to allow everything. Remember that Section 230 was part of the Communications Decency Act and was designed to ensure that websites could remove pornographic and objectionable content without being responsible (of course, it's also the only part of that law that was found constitutional, and for good reason).
By taking the only legal immunity for half-baked censorship away (i.e. private company gets to moderate what's posted but won't suffer consequences for getting it wrong) you've closed the door even harder on it- US law won't actually let you censor consequence-free otherwise, which is the whole reason S.230 was added in the first place.
