Then who, pray tell, would be the proper choice for the Guild Master? Couldn't be Laxus. He wasn't present. Couldn't be Gildarts. Not only is he not present, but doesn't want the job and wouldn't stick around for it. Couldn't be Mirajane either. As Levy mentioned, the guild master needs to be able to keep the guild members in line. Does she have the strength? Yes. Does she have the personality? No. I love Mira, but she's far too nice to be the guild master. And no one else in the guild has the power or the personality to lead. Also, you seem to be forgetting that when Erza was made the guild master, she was only made the guild master because they needed someone to be in the position to restart the guild, and she was the most qualified for the position. It's far from bad storytelling. Given the situation, it was the only option and it was by far the best option. And as far as Makarov goes, I seriously doubt he'd be angry. If what we heard is true, then this enemy is far worse than anything that they've ever faced before. I imagine he expects that his loyal, "hot-headed," "child," who happens to be one of the most powerful members in the guild, is going to show up.
