Why the islands of combat simulation already no allow to the damage?

I want to go into battle, but there are no places.

There are plenty of damage-enabled combat areas.  However, many of the most popular areas do not use the built-in Second Life damage system.  It's too easy to "kill" someone.  Instead, they use weapons and scoring/damage systems created by other residents.
