Replacing jobs with better or lower cost alternatives is not an externality.

Like if you switch from a low quality butcher to a higher quality butcher, you are not imposing a cost on the lower quality butcher.

You can not like it as a consequence of course, whether it is an externality or not.

Replacing 3 delivery guys with 1 drone maintenance guy imposes a cost on society if those delivery guys can't then find work.
