For the average person, yes laws are absolutely difficult to understand. We wouldn't need to involve lawyers nearly as often if laws were easy to understand and the process, defined by laws, was clear.
It isn't just about liberté for me. The law in discussion here may be pretty straight cut with regards to understanding what's on the page, but not with understanding what power the government is actually granted or when/how it will be enforced. The whole point in this thread was that the law is unclear as to how the government will define content posted online that may turn out to be inaccurate as illegal and worthy of leading to prosecution.
Consider it this way - if you handed said law to 10 people in the UK, would they all walk away with the same understanding of where the line is that they shouldn't cross?
