Because Smoker-san is an over confident BADA**with balls of steel!!! Looking back at the conversation between Smoker and Tashigi at Lougetown, he was a captain by his choice not because he wasn't capable of being higher rank marine. So, I don't think it has to do with his position in the marine but the logia DF power does add boost to his cockyness:))
