Mutual constitution is the model’s answer to the old opposition between the individual and the collective. It rejects both the individual exists for the ecology (which licenses sacrificing participants) and the ecology exists for the individual (which forgets that no one exists independently of the conditions that sustain them). Instead:
Participant and field are recursively constitutive — the field forms the participant, the participant alters the field, and each partly creates the conditions of the other.
The consequence that matters most is about growth. Because participant and field are not separable, growing the ecology is growing every participant, and growing every participant is growing the ecology — one movement described at two scales, not a transaction between two parties. This corrects any framing in which “the ecology invests in your becoming,” which quietly reintroduces the split: there is no second party, so your development simply is the field gaining capacity, in one of the specific places growth happens. It is also why a self-steering ecology steers by increasing overall ecological capacity: that is the one kind of growth in which the field and its participants rise together.
