What single company do you suggest can be trusted to maintain a listing of digital content that anyone can contribute to without censoring or interfering with the listing in some way?

We already know we cannot trust Google, Facebook, Apple, or Amazon.

And even if there is a company that we could trust, what happens when a censorious government wants something removed?

IP licensing can't be enforced outside of governments... Either you have enforcement and possible censorship, or you have no enforcement. The stated goal was to provide some form of payment system for content, but in a truly distributed system any valuable content will be paid for once and then reposted without payment required.

The ability to repost content without payment required is already true of every existing digital media distribution system. We do not claim to improve this situation.

LBRY does not provide IP enforcement. The primary reasons people pay for content when they could get all content for free are: 1) their personal morality and 2) fear of legal repercussions

The same will be true on LBRY.

We have Wikipedia, internet archive, library system that could be counted here as well no?

I'm fairly certain that Wikipedia does not allow anyone to upload a video or image and to my knowledge (though I'm less certain) the Internet Archive does not either. My second point would apply to both of those entities, regardless.
