The issue with this, of course, is that people have to know what's legal and what isn't. It's not equitable if we allow Google but we don't allow Bing, for example. From this principle arises stare decisis. Thus, under our current system, law becomes written one way or the other. It's very difficult to find the right balance between equity and flexibility.
