> Dunno why some people decide they get to nanny everyone else. There's plenty of other dangerous tools (when misused) to come after next if you go down this path.

We mandate safety features on plenty of dangerous machinery, most importantly cars - seatbelts, airbags, brake anti-locks, lane-keeper assists... or we ban stuff entirely, even if it is completely safe to use when one has the proper equipment and knowledge like asbestos.

The key thing is 30.000 accidents a year. Each of these probably costs society around 50k, and that's just the medical cost, not to account for (permanent) loss or reduction of income.

I agree that some will rig up completely unsafe "alternatives" but honestly, doing that rather than renting a safe saw for a dozen bucks... those people at least know of the danger.
