I think this form of analysis is amazing. It breaks the "The best solution was to actually cut out the parts of the page you don't want seen and then scan in the result." approach from elsewhere in this thread as well.
Even cutting out each portion of each line isn't enough because you can reconstruct line sizes. You could cut out each individual word and string them together, with a single size "redaction" block perhaps, but that's a lot of work.

Not really. OCR is plenty good enough to scan a document and then you can just replace anything you wanted redacted with a common string: [REDACTED]
Even if OCR wasn't an option, it would still (probably) be easier to type up the document than it would be to physically cut out all the things you want to redact.
