If you're just doing something and intend to meet or exceed the rules then dealing with government enforcement apparatus is pure overhead. You were always gonna do the right thing so you gain zero upside and have to deal with a potentially capricious and unaccountable (in any practical way) enforcer which is a huge downside.
Second, the rules are chock full of 10,000ft ivory tower view type stuff that makes statistical sense but is inefficient compared to using judgment. But you can't use judgement because the whole point of code is to make everything quantitative so that idiots can inspect other idiots and parties can more efficiently bicker in court and whatnot.
