The safe use of a table saw requires knowledge. Purchasing a table saw does not! Maybe therein lies the answer.
The safety of Children is the parents responsibility.
The safety of adults is their own.
Living is dangerous, most everything you do has the potential of injuring or killing you.
It is not your responsibility to remove everything dangerous from the media, where would you start, the Olympics, Gymnastics, The isle of Mann TT, all sports, the movies, YouTube, how about driving a car, riding a motorcycle, or the absolute most dangerous, riding a bicycle on the main road. What about wingsuits, anyone can buy one and jump off a mountain.
Is it your job to be a father to other adults?
What of personal responsibility?
Sometime around 1973 I watched a movie called "Little Fuass and Big Halsy" about motocross racing, went out that week straight to the Yamaha shop and ordered the biggest dirt bike that they made a SC 500 single cylinder, 500cc full race bike. A big change from my ten-speed bicycle. I had never been on a motorcycle before. I could very easily have been killed. Who would be responsible, Paramount, Robert Redford, the Yamaha shop or me?
Everything is dangerous!
As an adult I have to take responsibility for what I do, and that includes getting educated so that I understand what I need to know to try something new.
Keeping in mind that if you are alive you are always at risk of injury and death.
Personal safety is a personal thing.
The way that I have worked for the past 50 years would get me stoned to death on this forum. but it kept me safe* I have all my fingers and both eyes.
*I had one nasty accident 4 years ago when a router speed control failed unexpectedly, and instantly ramping up from 8,000 to 24,000 rpm, with rather nasty results.
The screenshot above of the Milescraft pushstick,, proves the very point that ignorance and safety devices wont keep anyone safe!
