    1. The problem statement, all variables and given/known data
    I just do not understand why Zwiebach can just "demand" that operators fail to commute like he does in 12.6 and just set commutators equal to what he wants? Why does he not have to prove 12.6?

    2. Relevant equations



    3. The attempt at a solution
