hosting that very sort of platform welcomes child pornography as is demonstrated by every such sort of platform or service that's come before it and I'm not talking about just the history of Tor hosting here. We used to find the same thing with free hosting, chatrooms and shell accounts in the 90s.

It's already a matter of law (in most western countries) that hosts have some amount of responsibility for what users of their platforms distribute and that's why other hosting services aren't structured this way.
