As we speak, power hungry nanny-staters are working to remove your freedom to use those things. There's been a recent discussion about table saws and look at the push for interlocks, speed limiting etc in cars. It's all part of a wide trend unfortunately.
Is an angle grinder safe? A tablesaw?
A car whose owner who uses the radio knobs, more than the steering? (Haha, unassisted driving, I mean! Walked right into that one.)
Etc, all of my examples have easily defeated safety mechanisms for an outrageously life-ending device ;)
