It doesn’t need to be as intricate as US law (which I not sure why that’s “baseline” for anything).

IMHO it would be better if it was as intricate as Roman law. Because while the wording might be intricate, all you need to know if something is allowed, disallowed, or required is to simply look at the law.

In the mean time, "esoteric" law systems like common law expect you to look at the precedents. That works in real life due to huge bureaucratic apparatus and recording old cases, but for a simple internet forum you won't get it.

EDIT: my point is that trying to make something "too simple" will bite you back later on, with even more complexity.
