Many things on God's Earth are fungible to one degree or another. Money is the classic example, being almost perfectly fungible. Oil under normal circumstances is mostly fungible too---a few nations refusing to buy Iranian oil isn't likely to hurt Iran all that much if they can turn around and sell to China and India instead. Similarly, even if we were to miraculously achieve 'foreign oil independence', we'd still be affected by the market as a whole, because American oil producers are perfectly happy to sell to, for instance, freezing Europeans with a taste for expensive diesel fuel irrespective of the opinions of Americans if the price is right.
But the sort of fungibility I'm talking of here today is that of people. You see, I'm arguing that the Cathedral absolutely loathes any kind of real diversity. If you're a counselor, for instance, the notion that you might be willing to counsel a person who experiences unwanted homosexual temptation in a way that doesn't glorify or affirm the lifestyle associated with such gives them hives. They absolutely hate the idea that in a free marketplace, Joe, who hates the fact that he is tempted towards homosexual fornication and wants help from a counselor grounded in a reactionary Christian worldview in dealing with the fallout and stress assocated with his struggles can do so, while Jack, who likes the fact that he is gay but wants help dealing with the fallout and stress associated with his lifestyle can also find an appropriate counselor. They hate the fact that some pharmacists refuse to traffic in some sorts of wholely legal drugs for reasons of conscience. They detest the fact that an artist might not want to affirm a lifestyle that they consider degenerate, or bake a wedding cake in honor of it. In short, they insist that everyone be fungible and interchangible within their particular role and class, even those elements who on the surface appear to have an exemption (woe to them when they stray off the reservation!). God forbid you start talking about free association.
The classic reactionary position on this is that fungibility is anti-human. Human beings aren't fungible nor were they made by their Creator to be such. Large corporations love this zeroth commandment though, for fungible peoples are less difficult to market to and manipulate, probably explaining a lot of the alliance of the corporate and the Cathedral.
