> Sometimes, even as a consumer, this is desired
I don't understand this argument. The goal is not to be intrinsically "slow", but to be suitably "careful". If you can be as careful as needed, but execute that careful process in such a way that no time is wasted, that's a win. The two are separate questions.
To put it differently: high-security systems programmers don't move their fingers more slowly on the keyboards because "going slow is better". They put checks in place, and they take as much time as is needed to do things right, but padding that time just for the sake of "slowness" helps nobody.
> Government is also inefficient by design. Imagine the gov’t pivoting to different laws every week - it would be completely unsustainable and would drive people crazy.
Speed of change has nothing to do with efficiency of implementation. I'm talking about writing laws that are efficient for companies to deal with, not streamlining the law-passing process so that legislators themselves are unburdened. It's a totally separate thing.
> inefficiency can be a feature...for big companies because it creates a slow and expensive hurdle for smaller competitors
This is true, and could be part of the reason this problem hasn't been addressed. But corporate lobbyists are just one of the many forces influencing legislation, and formalizing ideas around "efficient regulation" would only shed even more light on bad-faith attempts at making laws less efficient for the purpose of moat-building.
