I think that misplaces the cause. The requirement for safety and the high cost of failure is what creates those regulations and liabilities.
Theoretically, we could eliminate the regulations and liabilities and just let people die, but 1) that's a really bad idea, and 2) it would be excluding from the market mechanism (i.e., externalizing) the most important aspect of the product, its safety.
