I agree the race is real, and 300 million jobs is a serious number. But your prisoner's dilemma cuts against the ban. If defection is individually rational, a domestic ban just pushes labs to friendlier jurisdictions, leaving the regulated market weaker and the same capability deployed anyway. Open weights actually break the dynamic: once a model is public, no single lab can withhold it. So the workable move is policing clear harms, fraud, bias, unsafe medical advice, not outlawing reasoning itself. A radiologist in that rural clinic still reviews the scan. Capability bans are blunt; accountability rules are precise.
