You have some nice ideas.

You might not know this, but Steem doesn't actually protect your artwork. Images and Audio are not immutably recorded by the blockchain, they are stored on private servers. Only the text can actually be censorship resistant on Steem.

That said, your posts cannot be deleted by someone else, so even if the artwork is not actually stored on the blockchain, nobody can ever delete your posts that direct people to that artwork. :)
