You project some personal conception of "worth" of x as if it was some normative and objective value inherent by essence to each category x would belong to. It's not.

For whatever x, your estimation of the "worth" of x may differ from mine or that of any third person. The estimation of what x (be it a product, a service, or work time for a job) is worth to someone is inherently totally subjective to the eye of the beholder (be they seller or buyer, e.g. employee or employer… or external observer) and situation: The price that you'd be willing to pay out of your pocket for someone else's development work is likely much lower to the price you would ask for you doing the same work.

You're free to set your personal subjective estimation of what your work time is worth at, say, a gazillion dollars p.a. For whatever reasons, justified or not to others. Doesn't change the fact that it may or may not not be subjectively "worth" that much to people who are in principle interested in buying that work (though not necessarily at that price). For whatever reasons of their own.

There is no such thing as an inherent objective "worth", only subjective "worth" in the eye of each subjective beholder. All of that is totally subjective.

Objectivity of "worth" only exists in the purely observative statistical sense: In particular, "market worth" is simply the term for the value at which statistically two sides (each with their own subjective "worth" estimation) mutually consenting to the transaction find together.
