Literally every "I started touring really early on" contains at least one, oftentimes multiple, "these things very nearly killed me but they didn't because I was lucky!".
What happens if you're not lucky? Oh right, you end up injured, paralyzed, or dead. Like Ozymandias. Seriously, everyone recommending people go out and tour as a new rider should read at least 5% of the words written by someone who was killed by doing just that. Just read 5% of the words he wrote about his experiences as a new rider,excited about the world, cut short by inexperience, leading to paralysis, and his eventual suicide as a result of that.

Then think of those people's families, telling them their father, husband, son, whoever they may be, are now no longer with them because we as the experienced adults in the room, told them to go do something risky at the highest point of risk in their career.
You will find a distinct divide in the opinions on this between the people who have seen someone die in front of them, or watched an accident caused by inexperience pushed too far, too fast, and those who haven't.
Believe whatever you want to believe when it comes to yourself, that you're the exception, you're the ubermensch, you're just that good, whatever. But at absolute best it's ignorant to tell a new rider to go do their highest risk miles far from familiar roads, in new environments, at the mercy of the elements with no support and no experience to navigate those experiences.
And this isn't the old days, either, where a powerful bike made 40-50hp. The "widowmakers" of the previous years would hardly be compeition for an SV650, let alone a modern supersport. The fast bikes of yesteryear would be thoroughly trounced by the firebreathing beginner bike that is an SV650. So it's not really fair to compare the people who survived big trips riding slow bikes decades ago to those modern new riders.
