Why are they rebooting Batman again?

I am officially convinced that the people in charge of Warner Brothers
are stupid. They are planning on rebooting the current Batman series
after the Dark Knight Rises comes out JUST so the new Batman can be in
the Justice League movie (for those of you that don't know, Justice
Leauge is a series of comics about all the superheroes of the DC
comics, like batman, green lantern, aquaman, wonder woman, and that
guy who's weak to a rock living in the same world and working
together.)
Yes, I am a batman fan-girl. But I would assume that all of you fan
boys/girls of the other superheroes don't want your superheroes world
to co-exist with others right?
That's not the point, this batman series, whether you like to admit it
or not is phenominally succesful and popular. The good news is that
this batman from nolan's series won't be in the Jusice League. But WHY
reboot?
WHY include Batman?
WHY even bother making the Jusitce League Movie?
If warner bros was smart, they would continue this batman series with
a new actor and director to continue, maybe just have batman years
later in gotham. That way, the different actor could look slightly
older or different and you could possibly include more realistic
versions of characters like Batgirl or Nightwing. NOT ROBIN.
If warner brothers had common sense, they would realize that more
batman films would make SO MUCH MORE money than a Justice League
franchise would. Jusitce League would be popular with fanboys and die
hard fans, but not the people who don't follow comics or heroes in
particular and just wanted to see the batman movie because it looked
interesting to them. The justice league would also have FAR less
women/girls and older people in the theatres too than individual
superhero movies would becasue there would be too much to follow.

I just don't get how or why warner brothers are rebooting batman and
making a justice league.....are they really that stupid?
Metalc...if that is the reason, that WB wants to make more money, they
would continue this batman franchice? It is obvious this franchise
would make FAR more money than a Justice League series. And so what,
Nolan doesn't want to return, get a new director who is willing to
take over
