Imagine a world where people only bought bespoke suits. You go to a tailor and are measured and pick out your fabric and wait a few weeks. Then you pick up your suit. It's perfect. You pay $5000 and take it home.
Most of us don't do that. Most of us make due with off the rack suits with some tailoring for 1/10th the price.
With programming we have an expectation of bespoke design, so anything less, even if it's much easier, seems lame.
A potentially useful reframing of the question is, "What are all the common use cases that could be solved sufficiently with significantly less effort using visual programming?"
