"Punctuation has a purpose, use it."
Up to a point...
Punctuation (or lack of) has been what several legal cases have hinged upon - especially commas.
It isn't helped by the issue that fullstops or commas can be smudged in reproduction (faxing) or disappear entirely.
That's why lawyers don't use it and why their sentences may seem overly wordy when a bit of punctuation might make them shorter. It's all about avoiding (or causing) ambiguity.
Simpler version: If interpretation of a sentence changes depending on punctuation, then the sentence needs revision. (Let's eat, Grandma/Let's eat Grandma)
FWIW this is one of the reasons why English is regarded as such a difficult language and why engineering cockups happen so regularly compared to engineering in other languages.
