I think one has to put things into historical perspective. How free were we in previous decades? Up until the 1960s whole segments of our society had little freedom, they couldn't gather, vote, speak etc without being detained or harassed by government officials. Books were banned and censored.
Until fairly recently, most of us couldn't carry firearms legally, certainly not openly. In many places you couldn't buy them without all kinds of restrictions. While many places still have restrictions, many restrictions have been removed. Many kinds of weapons were not available back in the day until they were allowed to be imported, then banned, then allowed again.
From my perspective, while flying and other things are far more restrictive, overall personal liberties have increased.
