He wouldn't have liked it, but I think you are being too literal and less than charitable. She clearly meant something like becoming-decoded or working at undoing capitalist coding.

No, it's exactly the opposite. I agree with Shag: it's deeply materialist. Instead of assuming that capitalist command works because people lack the nerve, will, or organization to throw it off (as soft materialism believes), it recognizes that it works at all levels of existence, not just the obviously economic ones, and that we reproduce it every day in our actions, relationships, etc. This is the meaning of the quote Angelus passed around: Capitalism works because you do. There's no moralism in that; instead, it's an acknowledgment of capital's working in every pore of society, its ability to touch every aspect of our lives. But it's also an acknowledgment of its limitations: it always relies on reproductive labor it can never fully control.
Monetary policy and full employment are not the only ways to elude that control. Struggle works too.
