A lawyer.

Scanning dense legalese and/or contract language becomes quite a bit easier if you have an easy visual cue where the current (tortured) sentence will end. It provides a decent estimate for the upper bound for how much context and/or state you need to keep in your head to process a given statement.

I get to review technical and security parts of contracts at work and can see the value for such a font in that particular case.
