 One consideration in favor of  (RI)  instead of  (CMB)  can be derived by considering a “flat world”, a world where everything is independent, either in the sense of  (AI)  or (RI), and nothing is built, to use Bennett’s notion (Bennett 2017: 123–124). In a flat world, nothing determines anything else in the sense of (CMB), since nothing depends on anything else. In this case, everything is included in the unique minimally complete set. So, it won’t make a difference which definition of fundamentality we use here; we can say that everything is fundamental in the flat world both in the sense of (AI) or (RI) and in the sense of (CMB). That’s because the independent entities are in the unique minimally complete set due to their independence, not the other way around. Notice that for this to go through, the interpretation of (CMB) along the lines outlined in the previous paragraph is required, i.e., it’s not crucial that the fundamentalia do any determining.
