So to say in a communist way. Those who are more equal are the powerful?

Can be one expression of power. I think being able to do stuff is power too. Liberties on is actively acting in are powers I would say. Like to meet with others discuss, plan something and do it.

Generic speaking I would frame power to align reality to my needs. And even the most known "powerful" people like Putin, Trump and Xi are not powerful in every way. FOr example they often do not have the power to go partying without bodyguards or having a picknick in whatever Park spontanously. Or going somewhere unrecognized without masking up.
