All physicists acknowledge they are composed of atoms, duh! It does not follow that "if a set of atoms can be in a superposition, so can you." Here's some ways it might fail: 1. In the objective collapse theories, quantum systems undergo collapse when they reach a certain size. I cannot be in a superposition because I am physically too big. 2. In the ensemble interpretations, a quantum state applies to a set of many identically prepared systems. Since there is only one of me, we cannot speak meaningfully of my quantum properties. Admittedly neither of these are satisfying interpretations, but they have their proponents. The deeper objection is that "you can be in a superposition" risks detachment from experiments. If we cannot talk about the result of an experiment, that we cannot do science.
