> If people don't have an inner voice, it also must be the case the some people (these people?) don't have consciousness.
Don’t see how you got to that.

If something as (ostensibly) fundamental as an inner voice is "optional", chances are that consciousness is also optional.

The obvious error here is that an inner voice is not fundamental, and the fact that many people describe their consciousness in such different terms makes it much more likely that consciousness is just something that manifests in a variety of subjective experiences.
