That’s a terrible analysis.

I assume the “cost” were injuries added up through remaining lifespan through lost work, etc.

But you can’t do a cost-benefit analysis without counting benefits.

So let’s add up all the benefits and value created by table saws.

True, it's not apples to apples to extrapolate downstream costs of accidents while not doing the same for the benefits. All manner of housing and construction would be much more expensive and slow without ubiquitous affordable on-site powered saws - not just reducing everyone's spending power, but also median quality of life with everyone's daily spaces severely limited by design/build potential.
