Good automated (or even partially automated) inpainting would probably be a godsend for typesetters, since they can spend a considerable amount of time on a single page if it has lots of text or detailed illustrations. I imagine the publishers that put out multiple print volumes a month would probably pay good money for it, but it might still be too small of a market to build commercial software for...

In the worst case even skilled typesetters can spend an entire day cleaning up and typesetting a particularly nasty page if they have to repaint lines and blank out dozens or hundreds of kanji (it happens)
