Good cost you in ways other than their price - unsafe electrical goods can burn down your house, leaking your personal data can cause you to be robbed or defrauded, food can cause poisoning, etc.

So you might save $5 on the price of the "smart doorbell" and then loose $50,000. Obviously there is some kind of balance that needs to be struck, but the amount of data leaks and fraud is plain out of control at the moment,

Same applies to food regulation, restaurants, supermarkets, goods that don't last the warranty time,....

If a business cannot manage, it closes, as simple as that.
