Punctuation, other stylistic rules: obstacle or opportunity?

Punctuation, and other stylistic rules, with all their exceptions and apparently arbitrary forms, can seem like a massive obstacle to writing. If you’re unsure of punctuation (which is reasonable, given all the conflicting opinions on punctuation), the rules are more than a nuisance; they conspire to break into the writerly flow with their demands for figuring out, for example, where to put a comma. Punctuation and other rules are enemies to many writers. Certainly most of us don’t enjoy reading Strunk and White or the massive style manuals that define proper writing style in many academic fields.
