Everything is NOT a market, that’s a profoundly ideological statement. Check out Karl Polanyi and the distinction between a society with markets vs a market society. We live in a market society, but that is a historically unprecedented state of affairs - historically, many important aspects of society were distributed and regulated through other social forms. It is capitalism alone which commodifies everything under the sun, including land, housing and labor. Many of the most awful aspects of our society are rooted in this historic aberration and the creative destruction it brings with it.
Specifically the interests of the unborn cannot be represented in a market. The unborn have an interest in the use of resources and the exploitation of the environment, and it is a legitimate moral interest, but they are not market actors and their interests cannot be accounted for in a market framework.
