Simple, easier to rig, inexpensive and good looking.
You pointed out that some people may not see rigging as an issue. When I had to rig my boat and a boat for each of my son's each time I went sailing it was.
For the parents that brought their kids to the sailing school it was. For the kids it was.
In this modern world of instant gratification every step that moves sailing in this direction for the young ,
until they are hooked, will help.
If you could find the time to read my rather lengthy post above you will see from my perspective it's all about the ones that get away.
I am at this point through my own experience as a sailing father with sailing son's and when I came up with this concept I was the head of a sailing school.
I am sure there are many people out there with different experiences that all lead them to believe there are different solutions to the problem.
To these people I say- please get to work and start implementing your solutions.
That is what I'm doing here.

I will be happy to be proven wrong provided you are proven right.

At the end of the day the result will be the same.
