Noone has claimed getting structured data out of pdfs are sane. What you seem to be missing is that there are no sane ways to get a decent output. The reasonable choice would be to not even try, but business needs invalidate that choice. So what remain is the absurd ways to solve the problem.

Well, perhaps you are exposed only to special snowflakes of pdfs that are from a single source and somewhat well formed and easy to extract from. Other, like me, are working at companies that also have lots of PDFs, from many, many different sources, and there are no easy ways to extract structured data or even text in a way that always work.
If you actually read what I have been saying and commenting, you would realise how silly your comment is.
