I have some quibbles with these definitions. Capital is defined financially, in terms of market capitalization. Capital has a second definition as the means of production. Put another way, we can say, the “resources employed by businessmen to produce a profit”.
CasP theory explicitly rejects the second definition.
For the single best CasP discussion addressing most, if not (more than) all, of your points, see Bichler’s and Nitzan’s 2015 article Capital Accumulation: Fiction and Reality. https://bnarchives.yorku.ca/456/
If you haven’t already done so, you may also want to read the 2009 book, Capital as Power: A Study of Order and Creorder, which is available in its entirety (and for free) here.
