Why when creating new GameObjects I can't move them in the editor when the game is running ?
Move them I mean drag them in the scene view window when the game is running. The new objects myLine won't move.

In the line renderer parameters, disable Use World Space and you can move your game object

You right and I did it already. The problem is when disabling it the lines positions changed. I can't figure out how to re position them back to the original positions before the disabling.
Now it's working great. But I wonder what did you change ? I can see you added the line:
lr.useWorldSpace = false;
And removed the line:
myLine.transform.position = start;
Have I missed any other changes you did then my code ? I'm asking just for the knowledge to understand better :)
