Sure. If you got a very well behaving (and systematically scrutinized) executive and a legal system that protects the rights of each individual. The reason states shouldn't be given every power over their citizens just villy nilly is because power in a free society is given by the citizens. And if the state can target those indiscriminately without due process that is no longer the case. So it can make sense to withold certain powers from the state, even if with trustworthy leadership and actors these powers would be useful to keep the people in the state safe. And that is because untrustworthy leadership can come around at any point and then you don't want to give them an operational surveillance structure that would have given any authoritarian in history the shivers.
