That's a pretty broad question, and it seems like you have some misconceptions about what "agile" means (although everybody has their own definition). Which parts in particular do you not see the benefit of?

Why do people have to leave documentation
They don't. It's a common misconception that in Agile you produce no documentation.
What is true is that when you switch to an Agile approach, you will quite likely produce less, and different forms of documentation than before.
Documentation as such doesn't actually have value. It only has value when it gets used. And that is because the actual value is in getting the information in the heads of the right people. But documentation is just one way to do that. Often there are alternatives that are actually more effective - face to face communication, close collaboration in a team workspace, "executable documentation" such as a suite of Acceptance Tests etc.
and sit in a room & do just anything & everything.
I haven't yet found a developer who didn't like working in a team room once he tried it.
Not sure what you mean by "doing just anything and everything". Care to elaborate?
I agree it is faster but do not fully agree with any other benefit.
In my experience, being faster is actually not the main benefit of Agile. To me they are
* higher quality
* earlier return of investment
* earlier feedback and quicker reaction to new situations/learning
* more fun
If I would have been in an agile process, I would either have sacrificed my family or left the job!!
Again, not sure what you mean by "having sacrificed your family", or why you think that's what would have happened...
