This thread's been really interesting, I understand why people get so passionate about it because I'm passionate about riding my bike.
I've grown up riding trials, mostly motorbike trials and competed 90% of Sundays for the last fourteen years. It's fun, i wouldn't get out of bed every Sunday if it wasn't.
And here's my point, riding your bike (any bike) is supposed to be enjoyable, it's meant to bring a smile to your face.
Surely if someone is riding their bike and having fun then that's enough, It doesn't matter if they've got brakes or not.
Personally I think it's close minded to write something off because you don't understand or aren't interested in it.
Different people ride bikes, and generally live their lives, in different ways. The world would be a pretty monotone place if we didn't.
I ride with brakes, I'm not very good with them on so I'd most likely be awful without them, but when i watch brakeless riding it blows my mind because I can appreciate how difficult it is.
Life's short, lets enjoy it and not worry too much about putting things in boxes.
Just my two cents.
