Admittedly I haven't looked at the handbook for a couple years, so would you kindly just post the section? I've read all the Minnesota vehicle codes I can find and none prohibit it. I believe, while meaning well, you're just mistaken. If I'm wrong I'd like to know by seeing the section.
I'm sorry I still don't see it.

it does happen i was correct on one law. It is illegal to cross the stop line at a controlled intersection and stop waiting to make a left turn as stated here: Intersection Gridlock (M.S. 169.15)
Prohibits a driver of a vehicle from entering an intersection controlled
by a traffic-control signal until the driver is able to move the vehicle
immediately, continuously, and completely through the intersection
without impeding or blocking the subsequent movement of cross traffic.
(Effective 1/1/2011)
Solid white lines near intersections indicate it is illegal to pass within 100 feet of the intersection

Ever heard of a "Michigan Left Turn" ?
seems complicated
