A year is a long time. If it took a year to comprehend all the laws that you might be breaking, you're guaranteed to at least break some of them.
This is as opposed to the lifetime+ of our current set of laws? I'm not saying a year is a good number, just that it's a better goal to shoot for than we currently have (more laws apparently == better).
Makes a lot of sense to me, personally. Though I'll grant that won't happen, it's an ideal to shoot for, instead of endlessly patching problems with laws that noone can possibly comprehend the ramifications of due to the system's complexity.
