How is this different from saying "Banning mechanical farm equipment does increase efficiency, it makes it more efficient for farm workers to afford to survive"

You are fighting against productivity improvements when you should be fighting against people hoarding the benefits of productivity improvements.

That doesn't answer my question. My claim is that people working is efficient.

A carpenter using a hand saw instead of a power saw just to keep more carpenters employed is not being efficient. It's Pareto-better to keep all those carpenters employed, earning the same salary for fewer hours.
