Thank you for some original and interesting thinking. As someone who is, to be frank, consumed with the issue of power v. justice, I’ll be saving this for further reference.

Please allow me to recommend to you “Welfare Economics, Power, and Property” by Warren J. Samuels in “Perspectives of Property,” edited by Gene Wunderlich and W.L. Gibson. (I’ve found that a law library is likely to have a copy of it.) In it he all but defines defines “social power” as the ability to effect choices. He employs the concept of “opportunity sets,” i.e. ad hoc combinations of the stores of resources we have at our disposal to (attempt to) effect desired choices.

In case you might be interested, in developing an original approach to justice I’ve extended that idea of social power to define the political process as the process of effecting choices for the community as a whole and worked out a way to divorce a guaranteed income from capital or taxation: “Real Justice” (a “5 min read” here in Medium).
