You can say the same about law in general, yet law isn't "simple and explicit". It is very complex, hard to grok, therefore only a small amount of people are able to, leading to expensive lawyers and a law system which the poor cannot afford (ie. class justice).

Yes, ideally I also want laws to be simple and explicit. I'd even argue that worked quite well before globalization. Now it doesn't anymore. We need to adapt.
