which would be again completely random and therefore intransparent for 
the user, in my opinion.
If the user marked all vacation activities private because of all the 
private pictures... and then wants to mark the last open activity with 
his bank details private - and schwupps - action denied... would not be 
understandable.

hmm, the only usecase where we need a "normal, non private" activity, is 
when the user locks the screen with a private activity and doesnt insert 
a pw - then he would be blocked on the lock screen, because of no fallback.
Second usecase would be the case that all activities are private, then 
the user needs to enter these passwords to launch one activity. If he 
doesnt enter any pw, what is displayed? Black screen?
