Without it, there is likely no Hacker News, nor any other social media.
My believe is that if this is forced into a take it or leave it scenario, we're not going to like the outcome.
Which, come to think of it, might be a net gain to society overall. Hard to say.
I think the first priority is to ensure that the poster's misinformation (i.e., telling people that 230 says/does something it is explicitly designed not to do) does not propagate through this medium. It's a public forum, not a conversation with just the poster.
Then, if possible, you can engage with their disfunction. But given the weaponized role of misinformation today that's the first item in the checklist to be addressed.
From my viewpoint, it's very likely Section 230 will be modified. Once that action is underway, you'll be well behind the curve if you're just starting to grasp what people want. Others will have taken that time and effort and figured out how to mold it to their own ends, and the momentum will be building.
Usually it seems to be they're really saying "this shows section 230 is a bad idea."
If we could move past the reflexive "well actually" there's a real issue people feel needs to be addressed.
