I don't think you do get the point - the point is that unless you define every single word in a rule (like how legislation has a definitions page), it's very hard to do simple content moderation in a way that everyone agrees
Such that, if your model of how rules and regulations work is that they are all active at all times.... I have really bad news for you. For fun, consider that there is still the 18th amendment to the US constitution. There is just also now the 21st amendment to go with it. And at no point did we have to redefine words for that trick.
They think I didn't get the point, but they're wrong. Hope that helps!
I have a lot of experience thinking that I get the point of someone else's argument, and then realizing later that I didn't actually get the point, or not in a way that was useful to both parties in the conversation
When I don't feel understood it's usually because the counterparty hasn't said things that allow me to recognize that they have internalized what I'm trying to communicate
Changing tack a little, I think that this is one of the things that I admire about some legal writing, that they are intentionally addressing the act of communication in addition to the substance of what they are communicating. In addition there is a recognition that their words have consequence
