My usual answer to VWH concerns is that it unreasonably assumes that we can align global states and make sure they stay aligned. The default state is a narrow interest group usually takes it over. Also, states have more reason to pursue black-ball technologies like nukes, pandemics and more, and it has no incentive to pursue gray or white-ball technologies, so a global surveillance state will in time try to kill billions based on narrow interest groups.
