>In theory, all regulations need to be carefully considered and walk a fine line in order to do more good than harm.

Yes, and one of the possible definitions of a (technical, safety related) regulation is "the added cost that the society is reasonably willing (or capable) to pay for a reasonable increase in safety"

The issues always revolve around how much the "reasonably willing to pay" is and what is the corresponding "reasonable" increase in safety (and how exactly to measure the latter).
