There's two nuances I would respectfully suggest that you're overlooking.
First, KRNC is designed to be employed as a supplement to USD. Most transactions would be executed with both USD and a corresponding blockchain asset. Technically, this is a digital analogue of the "symetallic standard", in which base money is comprised of both gold and silver in a specified ratio. The point is risk diversification: if fiat money implodes, or if crypto fails, you aren't wiped out.
Second, the concept of "intrinsic value" is misleading/confused when it comes to money. Things that trade at their consumption/production value are not monetized. Treating something as money involves attaching symbolic value to it: accepting it as proof of goods or services rendered in the past, and as a token that can be used to acquire goods or services in the future. Even gold would lose most of its value if it were suddenly priced based only on demand for use in industrial applications.
Money has always been valuable because everyone else treats it as money, whatever it is. It's a Schelling point that enables abstracted barter. Nothing less, nothing more.
