If I decide to stop buying bread from the baker in boycott, is that a commission? It is certainly a change of state, but the status quo does not entitle ongoing purchases. This is a sanction. I can also extend this boycott to anyone else who shops at the baker. That still is not a commission. It is a refusal to interact.

A blockade is different. It is a threat to use force for disobedience. IF I threaten to beat other who willingly shop at the baker.
