> Yes, but even if you create a regulation that is $40k more expensive to implement than the cheapest option, it still results in a $49.95M in savings (regardless of who would be picking up the bill, at least when you consider us as a society that depends on each other to function) compared to having not set up that regulation at all.

Which is why those kinds of regulations are the ones you want.

But it's still worth carefully revisiting them from time to time, because $40,000/company/year is still literally having each company hire a person to waste their entire working life. This is what regulators should optimally be spending most of their time on -- evaluating the existing regulations for ways to reduce the costs without losing the benefit.
