How many people who buy a car ever bother to read the few hundred page manual filled with all sorts of useful stuff and information, including safety information and warnings? Still, while a significant number of people do overlook that helpful manual, it is appropriate that it's provided. It is also appropriate for common
sense regulation to assure it HAS to be in there, even if a segment of buyers are too lazy, or unable due to illiteracy to ever read it.
How many recall letters go out about known defects in cars (and lots of other products) yet many will simply toss the notice out like junk mail and never do something simple, like get their brake lines fixed for free before they might fail? Of course, if and when they do fail, they'll still sue the car maker (or whoever) claiming they never received proper notice or notice that was understandable (it's a sad commentary on our society, but not only do we not have close to a 100% literacy in this country, our rates trail many developing countries with far fewer resources).
Regulation cannot substitute for information and education. But given the real world we live in, regulation is required to attempt at least a modicum of safety in the marketplace. It will never go away. It should be kept to the minimum required to achieve a reasonable reduction in risk to the public. It will never eliminate all risk, and should not be designed with the intention of doing so as it is an impossible goal as risk can never be eliminated in every circumstance.
In a real world context, I'd rather have a regulation for a printed warning about proper battery use than a regulation banning replaceable
batteries in something like a mod as too risky to be allowed on the market. There will never be zero regulation, so the goal should be a thoughtful process of what is a reasonable set of regulations that do not burden business or users with excessive and overly restrictive requirements.
