This advice appears based on deficiencies in programming however. Programs operate on algorithms to process data. When the programs or algorithms fail to be able to do so properly the program is at fault.

In your cases you have items like: accounting, building codes, tax codes, automobile codes, etc.

While it makes sense to try and harmonize with the general policies, every state, every municipality, and every business is going to have special cases. Even software has edge cases for protocol behaviors.

What would be nicer, imho, is if all of these laws were written in domain specific languages that specify the law and then the software could just pick up the definitions signed into law. Lawyers as they are feel like a combination of legal interpreters, combined with a combination of being red/blue security team members depending on what they are doing.
