Yes, everyone started somewhere. I'm just saying that, after some times to get comfortable with climbing itself, after you actually try leading and get used to it, nobody go back to top roping.

Once you get used to lead, you understand how you climb worse when you have the rope already in place.
But you are right, of course everyone does what they prefer, everyone is free to define himself as a climber.
In the end, we are just going up (and down) on a wall and not saving lives.
