The common sense approach to intermediary liability is what was already in place before the CDA turned everything upside-down. If you're an intermediary, there's a trade-off to be made. Either exercise creative license in your mediation of user communications, and be legally liable for that, or don't, and stay free of liability. I think that makes a lot of sense, and would have been totally fine on the internet, and was totally fine until 1996. It allows for all the same business models that were growing and thriving until 1996. It didn't impede the economies of scale that were unfolding and continued to unfold. Then, in 1996, the internet began the process of de-linking, de-indexing, de-listing, shadow-banning, click-baiting, and pay-walling. And "communications decency" was definitely not achieved, either.
