Division by zero is undefined and it not guaranteed to correspond to +infinity in all context. In this context there might be a difference whether we are talking about the limit when labor apporaches 0 and when labour is completely absent.
True, and in this context the limiting value when approaching from above is certainly the appropriate interpretation. After all, we’re talking about a gradual transition from current use of labor (which is positive) to zero use of labor. If the infinity is still bothersome, imagine somebody is paid to spend 1 second pushing the “start the AGI” button, in which case labor productivity is a gazillion (some enormous finite number) instead of infinity.
If you are benetting from a gift that you don’t have to work for at all it not like you “work at infinite efficiency” for it.
You seem to be arguing against the definition of labor productivity here. I think though that I’m using the most common definition. If you consider for example Our World In Data’s “productivity per hour worked” graph, it uses essentially the same definition that I’m using.
