Power itself is an imbalance. It implies the non-universal capability to do something. When we say "the president of the club has x, y, and z powers" we're not talking about the things everyone else in the club is able to do.

So to be opposed to "power dynamics" is to be opposed to non-universal capability, an extremely radical position which I am not sure you hold.

Could you expand on your definition to clarify your position?
