Ya, no. Besides the horrendous patent issue (say goodbye to market competition), this will double the price of table saws. No thanks. Consumer protection laws are not about making obvious choices for me. Its supposed to protect me from the unknown unknowns - things that the average consumer would not know is dangerous. Everyone has heard about these safer saws for over a decade now. Everyone knows saws are dangerous.…
If it becomes mandatory I wouldn't want manufacturers and customers to pay more. You could cancel his patent, but I think why not let the inventor get his "reward". I would take the money for licenses and implementation from health and disability insurers.
Of course, our system is really bad in making these kind of sensible re-allocations, so that probably won't happen.
