Driving has long been considered a privelege, not a right. Your

Do you consider using a table saw a right? I'd classify it as a privilege too. There is some document written hundreds of years ago talking about the pursuit of happiness. Maybe table saws fall under that saying. Using table saws is a privilege. The government can mandate insurance and/or safety devices.




Can anyone give an example of a law that required using a patented, licensed device?

This question still stands. Does anyone have an example of a government mandated device that was still under license and restricted? ABS, airbags, seatbelts were all public property free to everyone when they were mandated.

The notion that airbags and abs were"public
property" is based in the rather naive notion
that patenting a device that has a certain
function makes it impossible to patent
improvements in such a device. If the airbags
or antiskid brakes that were originally patented
were actually viable in the market they would
have gone into widespread service much sooner.
The fact is that neither went into widespread
service until patented technology was developed
that made them sufficiently inexpensive and
reliable to be viable in the market.
