Because no attempt was made, I'm surprised he called it.
Over the years, I've found it difficult to protest a non-call.The OP asked "at what point does it become obstruction". The rules are consistent, unlike "how they're called". Bad calls are often a reality many of us choose to live with, sometimes due to ignorance of the rules and sometimes because there is no point in arguing it, but with an uderstanding of the written rules we have the knowledge to protest in situations we choose to.
I do understand the rule.
