Are real rights subject to revocation by bureaucrats until one successfully appeals in court?
Well, effectively, yes. If your name is erroneously purged from a voter roll by a state employee (something that has happened in many, many states), then going to court is what it usually takes to get it restored.
I mean, that's the point of courts - not to make sure no right is ever violated, but to fix it (and sometimes provide recompense) when it is.
