'Must' just means being required to do something, not being required to do soemthing by law.

No you don't know this. You continually state that the law is telling you how to live, and you therefore have a right not to obey it if your decisions thereof conflict with the law. I am saying that the law does not try to tell you how to live.
Yes, I do. I never stated anything like the words you are trying to put in my mouth.

It is not a matter of 'having a right' to disobey the law, it's fundamentally not what your decisions are based on. I can't imagine that any sane person would make their decisions purely on the basis of what was legal and illegal. The law is a factor in your decisions, but it is not the cause of your decisions.

'Rights' as we call them are just a made-up, fuzzy concept that has sprouted from civilised society. We are not born with innate rights, we are granted them by whatever legal system we are born into. Rights have nothing to do with personal decisions, it's personal ethics (what you want to do) and potential consequences (what would happen if you did that) that matter.
