There's a few things going on here, things we've discussed before, things that just might define the current state of our culture.
HUBRIS: You can do, we can help. You're smart enough to figure it out, so there's no need to bother to learn first. Tradesmen are automatically 'inferior,' so anyone with a "cool" job (like producing a TV show) need not respect their skills.
PRIDE: No longer valued. Slap it together and move on. Just so long as it looks good, and we can deny everything else. Promises, the 'sizzle,' matter more than results.
DESIGN: Why bother thinking, when you can cut & paste, or copy?
HONOR: The inspector won't see it, so ... all bets are off. Let's ignore any & all history that might have led to the writing of those rules.
It's not just academic. For example:
Near me is an Arby's restaurant that had a rather small fire. This led to a visit by the city afterwards, where it was discovered that EVERY roof joist had been cut. This was not related to the fire; what the plumber didn't hack apart, the HVAC guys did. The only thing holding the roof together proved to bee the layers of asphalt roofing on top.
End result? Building stands condemned. A massive remodel - probably requiring the complete demolition of the fairly young building- is necessary. I expect that the parent company, the franchise owner, and the insurance company are all spending a lot of time with their lawyers.
Yet, they 'got away with it' for quite a while. We all know of similar things. In my household remodel, it's amazing how many folks counsel me to do wrong things, justifying their position by saying there will be no inspections.
You can't fix stupid.
