Sure, the \break is not necessary to demonstrate the "lonely bar". Every 
time you use \startStaff again at the beginning of a system, the upper 
system has the bar at its end.
The problem with \once \omit Staff.BarLine is, that you must know, where 
your breaks are and you have to use it every single time.

"Can you give a convincing reason why this would be wrong?"

Why would you want to have a lonely BarLine without a Staff or musical 
content?
