Sorry my guy ignoring the ridiculous environmental destruction of LED light production, which includes semiconductors, metals, plastics, and control electronics, doesn't mean they're less costly. In fact, they take a huge number of additional people, pieces of equipment, energy, etc than an Edison bulb. Same with paper. Saying that reducing paper use saves paper is a tautology, and doesn't compare with the massive environmental cost of data centres and cloud computing.

Look, we've gotten off topic from LTV. My issue is around the background costs of production and how that relates to the profitability of products. I think your examples don't encompass some of the important parts of LTV, because they are focused for some reason on energy savings, and don't take resource extraction into account.
