Plenty of professional animators use rotoscoping. Modern CG animators often reference video recordings of themselves acting. It's just another tool, not some form of cheating.

Sure, but the linked post is titled "Balls to learning how to animate, let's film some parkour!"

That does not imply being afraid of it, but seeing is as too time consuming.

"Balls" here does not refer to courage, but is used roughly as a synonym for "bullshit" or similar terms.
