Thanks for the feedback. I agree that risk management is a part of project management. What I, perhaps unclearly, was communicating is that people and organizations can often conflate the two. A project is not managed if all you've focused on are the risks. They are related, but distinct things.
Let's take your example and apply it to my post. Imagine I need a new water heater. I found a contractor/company to come and install it. Should I assume the installation company will bear all the risks associated with a potentially problematic installation? No, I will carry some risk. Ideally, I would argue homeowners should familiarize themselves with the basics of correct water heater products and installation because if it fails outside of the installer's (or manufacturer's) warranty period the homeowner is liable for repairs. It's a stretch of an example because homeowners often share risk with insurers, but I think my point is clear - one should not confuse project management _with_ risk management.
