My issue is that you don't seem to include the value imbued on these commodities by their labor during their production.

You can play this game at any stage of the production cycle. Rather than describing the transformation of individual components into a finished motor, you could describe uncast steel transformed into individual components or iron and tin blasted into steel or undeveloped real estate transformed into iron and tin mines.

I assume you wanted an example that shows "wasted labor" but I'm not sure why, either.

To distinguish between the idea of labor mispriced and misapplied.

Nothing about modern technology is less costly than older technology

The number of lumen you receive per watt of power applied to an LED is significantly more than the lumen you receive per watt of power applied to a wax candle. LEDs are far cheaper to produce than candles, they last longer than candles, and they produce far less waste. Everything about an LED is less costly than a candle.

Those things have so many components, metals, semiconductors, plastics, heavy metals, etc in them.

I've got an LED bulb on the end of my phone that produces light equivalent to an old car headlight. It weighs less than an ounce, contains no heavy metals, and will last the full life of the phone. To produce the same amount of light over the same time period with a candle, I would need buckets of wax and miles of wick. And the sourcing of those materials would create mountains of trash. Nevermind the ecological impact of all that burning and melting of materials.

Also, I doubt that "conserving paper" by going digital is a net savings

In a country with 50M additional people, the consumption of paper products between 2000 and 2020 has fallen by over 30%. We are expecting to see another 10-15% reduction in the next decade, which amounts to 10M tonnes of paper per year. This, in a country that consumes 17% of global paper.

Paper is a renewable resource

The process of paper production has an enormous ecological footprint, both in terms of the raw destruction of tree life and the chemicals and energy waste that goes into the manufacturing process.

What does conserving energy have to do with labor value anyway

Activities with a lower energy footprint produce less physical waste and reduce future demands on labor to perform cleanup and mitigation of the damage that this waste causes.
