I actually like the teacher's approach of not having a rigidly structured seating arrangement. It's teaching the children to be flexible and adaptable, and also providing them with more autonomy in selecting preferred seatmates.
Except that once one student takes a seat, someone not desired takes a seat next to them, conflict (remember, the teacher is vocally advocating that the children learn the consequences of sitting next to someone distracting, as if they have 100% control over that somehow - utter nonsense). Someone else wanted that seat, conflict. Two or more kids want to sit near each other but can't find enough seats next to each other, conflict.
The teacher is probably playing referee for the first few minutes of class every day.
