One thing about "regular" currency, coins and paper: when it costs more to
manufacture it than the money is worth, the coiners/printers usually find
another substrate or technique. This happened for example, with US quarter
dollar coins some time back--they went from solid metal with some
percentage to silver to a cupronickel laminate.

Bitcoin "value" is based on speculation. Hard to see how the expense of
creating it would regulate the manufacturing cost.
