Yep, that's the problem. As a general rule, driving without a seatbelt is also pretty safe.. until it's not. The question is whether the advantage you get from something is bigger than the potential consequences.
I'd say, given the historical track record of governments during the last 100 years, that it's very gullible to believe that whatever future problems our current data sharing will cause will somehow be "fixed" and not have consequences just as long as it affects a critical mass of the population.
