> "Law" is a silly word to describe the regulation a legislative body puts to paper, in my opinion we should stop using it like that.

I understand where you are coming from, but you've got it backwards. Natural sciences adopted the word "law" to describe some "immutable" principles (that's obviously a descriptive use, ie. our descriptions of our understanding of some observations).

The word "law" comes from moral philosophy ("what is right?" and "what should we do?") and jurisprudence ("what is law?" and "what should be law?") of the ancient Romans ("lex") and is deeply rooted in the idea of norms (as in "normative", ie. that's how it should be) we, as humans, set for ourselves. Thus it is not silly to describe a regulation a legislative body puts to paper as law. That's what it means.

Note, I'm not saying you are wrong. It's just language changing and I wouldn't worry too much.
