How do you envision this helping?

There are limits to home inspections, and many types of defects you're just not going to see. For example, that leaking water line causing a brown spot on the wall that reappeared after a week could be slightly slower (or in a drier season) and only appear after a few months. Many problems take time to manifest as symptoms, and especially with a newly constructed home there just hasn't been enough time. (also why code inspectors check at separate stages of progress, while many more problems can be visible without having to open walls)

Furthermore, home inspectors don't actually have any skin in the game. They're not giving you any kind of representation or warranty, but rather more of a quick look from the perspective of someone who knows how houses are built and have a list of common problems to look for. And they can certainly succumb to the same type of normalization of deviance going on with the contractors in this article.

That's not even getting into the types of ongoing scams I've heard of where builders/sellers do things like "seal" the attic access door for "energy efficiency" reasons, and then assert that home inspectors cannot inspect the attic (eg the roof!) because opening the door would be causing damage. Or that a seller can easily cover up many types of problems a home inspector would notice, it's just generally illegal.

I'd say the real problems here are the high pressure sales funnel, and the complete lack of legal accountability. Forced arbitration and other onerous terms should be illegal. Heck if we're talking about a professional developer with an inventory, liquidated damages themselves should mostly be illegal. And newly built homes should have mandatory warranty periods longer than a year, probably at least 5 years, culminating with an independent inspector at the end to help notice any still-developing problems.

Then, claims for defects shouldn't be going directly to the builder who's strongly incentivized to trickle it down to some disempowered guy in a van, claiming to have solved the problem with whatever he had on hand. Rather the homeowner should be able to choose any contractor to fix the problem and file a claim on the builder's insurance - just as if it was home insurance claim, with a different responsible party.
