> The job of banging together reasonably serviceable form of shelter isn't that expensive. It's only expensive if you have to jump through a lot of hoops to use certified designs, materials, etc. deal with inspections, use expensive people for that have had training for wiring things together, etc.
"Reasonably serviceable" — ay, there's the rub!
The U.S. Navy's nuclear propulsion program has a saying: You get what you INspect, not what you EXpect. Certifications, inspections, etc., are meant to try to keep lazy-, sloppy-, and/or dishonest providers from passing off shoddy (or even unacceptable) work product.
In many areas, most customers don't have — and shouldn't have to have — the expertise or the time needed to inspect and assess providers' work product. By requiring knowledgeable inspections in critical areas, we increase the cost a bit, but we improve safety for everyone — which lets us non-experts spend our time more usefully. (It's a form of division of labor.)
To be sure: Certifications, etc., can be captured by industry groups and used to limit competition and increase prices. That's a separate issue, one that can be dealt with in other ways.
