If you give your governments tools that can be used for oppression, even if they aren’t abused today, it would make it easier for a new authoritarian government to abuse them later on.
Spain was a dictatorship for much of the 20th century and Argentina had had multiple military dictatorships too — it could happen again. Europeans are far too confident that they have overcome the problems of the past by building the EU etc. A bit more American-style distrust of government would be a good thing.
