That would make a lot of sense.

Scientific fields obviously put a lot of effort into tackling this problem, but philosophically, it is not possible to be specific enough to do away with vagueness. At some point, you have to use language like "a reasonable person" and just leave judges to interpret the spirit of what's being restricted.

So you’re perfectly fine with vague rules like that?

Yes. I don't even feel it's that vague.
