For that argument from privacy to work you need to provide reason for why flying is the only acceptable form of travel. Or why it is only acceptable to "get away" to locations to which flying is the only possible means of travel.

Realistically speaking, the only traveling you can do with perfect privacy is that which you do without involving others. If you use a travel service your desire for privacy becomes an imposition on the free speech of others.

Its exactly analogous to refusing to ring your fog bell on a boat while stuck in a fog bank, or refusing to use turn signals on a car.

It's not at all analogous. A turn signal tells the people around me that I'm just about to turn, not that I'm on a road trip from Chicago to Tucson. Nor is my entire turn signal history centrally logged and searchable.

There are two analogies:

- The broadcast of your location data is analogous to a turn signal.

- The FR24 community is analogous to a group capturing data about use of turn signals at various intersections and aggregating them.

Both are perfectly reasonable analogies.

And yes, it's completely possible for people using only publicly-visible information to put together your entire turn signal history and make it searchable.
