But the XKCD mentions kWh/day specifically, in theory the times can cancel out, leaving you with kW

But instantaneous and average kW are very different, and it would take more time to describe that distinction than to use kWh/day.

My freezer was labeled in max watts, kwh/day, and kwh/year. Because the cumulative watts over time is what I pay for my power bill. That way it's a simple multiplication that tells me how much having that freezer would cost.

Ok that's fair, I kinda glossed over that part. Both are valid interpretations, I think.
