The way I understand it is that subjective value is a function of knowing what the thing can do. I have to know how to make use of crude oil or it might have a negative value to me, like it did for everyone for thousands of years. Knowing how to use bitcoin (in the most basic sense) is a prerequisite to valuing it as a tool for savings or as a formof money. The knowledge required to value anything is not guaranteed & it is not connected to the thing itself, so there is no intrinsic value.
