Some seriously muddled thinking there, but it needs to be as it's largely about self justification and hypocrisy.
It really isn't up to an individual to decide whether legislation matters or not. The fact is that it is there. Like speed limits, you can decide to ignore the bits you don't like, same as everyone else, but it's not much of an argument in court.
Now, my personal view is that the law is largely an ass, and one is perfectly at liberty to break any that one wants, AS LONG AS YOU ARE PREPARED TO TAKE THE CONSEQUENCES. But what you can't do, once you've made the decision that you're only going to follow selected bits that suit you, is decide that other people haven't got the same right, just because they break bits you think they should keep. That's blatant hypocrisy. There's a lot of it about.
