 Returning to absolute fundamentality, you might worry that the above account leaves out an important dimension, specifically the fact that the absolutely fundamental facts are complete in the sense that, since they are the basic building blocks of reality, to describe them is in some sense to provide a description of everything (Tahko 2018). Note that absolute fundamentality conceived of as involving both independence and completeness seems to capture the notion of an unexplained explainer—the absolutely fundamental facts are independent and therefore unexplained, and these facts are complete and therefore explain (Bennett 2017: Ch. 5). Looking to the history of philosophy, we see that fundamental entities are regularly invoked as a means of meeting certain kinds of explanatory demands, demands that perhaps only independent entities could meet. This is typically evidenced by the arguments from vicious infinite regress that are commonly wielded in defense of them. It’s because we need to explain, for example, why there are any contingent things whatsoever that God must exist and, importantly, if God weren’t the terminus point of our regress—because independent—then the problem that God was invoked to solve wouldn’t be solved after all.
