You are completely missing the point. You can't just say "So what if a mechanic forgets to check the brakes to make sure they work before setting a customer loose in a car that is going to run off a cliff and DIE."

Insurance can certainly cover the cost, but is it your company's official stance that it produces coders who need to be paired with supplemental errors and omissions insurance policies because they will crash your company's product or that it would be ok if they cause major problems?

I think you are somehow confusing graphic design with software engineering and programming here. Maybe what you should be telling people is that you are teaching people how to build brochure websites for a living. If that is it then your perceived quality or capability bar might not be objectionable.
