I will share my opinion, which may prove inaccurate, but here goes...

You have to draw a distinction between the steemit website and the steem blockchain. Steemit may have to comply with the law if it is hosted in the US. Is it? I don't know.

But that doesn't mean a different website, say one dedicated to sex workers, can't use the API to pull certain posts from the steem blockchain, and indeed allow posts to be made to it. It could also allow posts to be made, comments to be made, have its own ratings system, whitelists and blacklists and its own featured posts. It could display all posts that use a certain tag, regardless of origin, or only ones that were posted using the site.
