Engineers (real ones, not software) face consequences when their work falls apart prematurely. Doubly so when it kills someone. They lose their job, their license, and they can never work in the field again.
That's why it's rare for buildings to collapse. But software collapsing is just another Monday. At best the software firm will get fined when they kill someone, but the ICs will never be held responsible.
At the moment you remove one of these factors, free market becomes dangerous for the people living in it.
