Not stupid exactly but certainly tempting human nature to bend better judgement.
I'm on the board of the local ski hill and when we deal with insurance/lawyers the phrase "inherently dangerous" always comes up as the category that skiing falls under. It means that even if best practices as recognized by experts are followed there will still be injuries - they are just baked in to the sport.
Kiting more broadly is the same as skiing, snowkiting probably more so, gliding exceptionally more so. I'm always reminded during snowkite season of how many factors need to come together to have enjoyable snowkiting - the right snow, high pressure vs. low pressure, light levels etc. It's an even tighter band for gliding (disclaimer - I used to do some beginner level gliding when I rode flysurfers and inflatables, now my standard wing is less good for it and I don't do much but would somewhat like to revisit it. Still do some big sent jumps on snow though).
This guy who dies last week seems like he was doing things mostly right - went to meet-ups, advanced skier, doing his gliding in moderate wind. Started the day doing smaller glides and then staged up. But didn't check for soft landing (forseeable) or maybe didn't anticipate being drifted over a hard area (grey area for predictablity)
So how many data points do you need to know what percentage of the time you may get out of control in the air? 50 low glides? How likely is anyone to get excited and want to go bigger after 10 or 20 low glides?
So, for now I am encouraging my friends to glide low and not to glide when the conditions are less than optimal
This is the most difficult trick of all if it's going to get scaled up as general advice. Some of my friends are cowboys. Some of my friends can't judge conditions for shit. Sometimes they haven't kited for two months. Sometimes (this can be the worst factor in judgement) they brought their new go-pro and want to put something on facebook that night.
Not really advocating for or against gliding really, just saying that everyone needs to take good care of yourselves and each other, think about the examples you're setting.
