It worries me a little, more in the sense that we're increasingly locking down our children and making it such that a person is either unable to or has little reason to be out in the world without supervision until they're eighteen; I'm not saying this bill is an especially destructive aspect of this shuttering, but the theater of it certainly adds to the "we must protect our children from the outside world" of it all. The fact that you can't really verify someone's age beyond a "yes I'm 18" modal adds to the theatrical aspect. A lot of arcane/fascist policy is bubbling up out of the concept of protecting our children, and as a child of the 80s/90s, golly, that sure sounds familiar.
It seems to me we should be addressing the issues which make the internet such a fraught environment for a growing mind; I'm not against limits, but those are the domain of the parent; ensuring the space itself is safe is what policy is for. I grew up in an environment where a lot of media/culture/ideas were cut out mainly due to satanic-panic-slash-stranger-danger-era fears, and that only drove me to pursue the forbidden. I didn't get hurt and turned out fine, but certainly put myself in risky situations. I learned far more about the world and how to be safe within it from experience than avoidance.
