Most office jobs don't involve that much typing. You can also buy keyboards with softer switches. (RSI was more common in the days of mechanical typewriters.) Low physical acitivity can be made up for going to the gym after work.
It sounds to me you never did a day of manual labor in your life.
My point, was that both physical/labor intensive jobs and office jobs bring their own types of workplace related problems. And just because the job may carry with it a risk of physical injury doesn't mean the job should be automated. Afterall, any type of movement the body does carries with it a risk of injury.
While your point is true that every profession has an injury risk, it's the type of comment that misses the point: there is a significant difference in those stats, and by trying to equate them, you are purposely watering down the significance of one where injuries are more prevalent (or at least harder).
It's a response similar in style to deflecting from attempts to solve one crisis by introducing another crisis.
I think you’re envisioning jobs with high skill requirements or low demand, or a mix of both. Like landscaper for the town, or garbage truck operator.
Otherwise you’ll generally be met with a combination of RSI, hazardous product ingestion (dust, paint fumes, exhaust…), allergies, injuries, or sheer overwork.
Working a low wage low level physical job is more often than not closer to Amazon warehouse worker than artisans healthily exercising their bodies.
