Elaborating on this a bit, I think it's less that things are less forgiving, but that our risk tolerances have dramatically shrunk. Millennial parents are less risk tolerant with their kids' safety, and Gen Z / A kids and young adults are more careful about the rules.

The root cause of this risk intolerance might be dispersed, just a cumulative result of cable news scare tactics, dropping birth rates and more investment per child, but I suspect a big aspect of it is that risk taking is no longer the only way to get a dopamine hit. Prior to the modern internet, if you avoided all the normal risk-taking behaviors associated with teenagers and young adults, you'd just be bored to death. Now the reward side of the risk-reward balance is just the difference between high-quality fun from meatspace shenanigans versus lower-quality enjoyment derived from social media and online gaming.
