This is wholly incorrect. The relevant section simply states interfering is enough.
§ 121.580 Prohibition on interference with crewmembers.
No
person may assault, threaten, intimidate, or interfere with a
crewmember in the performance of the
crewmember's duties aboard an
aircraft being operated under this part.
It in no way limits it (and I've never heard anyone suggesting it does) to simply following instructions for smoking/seat belt use. If you fail to follow a crew members instruction you are interfering, plus if depending on how you refuse, it can be intimidation.
