The need for "work" is still absolutely necessary in the physical sense. All we've done is replace human/animal labor with cheap fossil fuels. The only way it could appear efficient is with dishonest accounting - intentionally ignoring the physical basis of energy production and assuming watts are infinitely cheap and substitutable.

That sounds like The Matrix (the movie) logic. In reality, feeding humans is energy inefficient. If anything, it takes multiple watts to end up with one watt of human work. Dishonest accounting is pretending human/animal labor is free.
