You're just gullible.

There is no website that I've ever uploaded my driving license or other ID to, the only place that I need that for is my bank and that's about a real world relationship, not about an online one.

Any website that wants me to verify my age is going to have to do without me, that's just none of their business. What children see on the internet is not going to change because of this, any parent that wants to modify their kids' behavior is going to have to do some actual parenting rather than to rely on gatekeeping technology because kids are far more capable than their parents when it comes to circumventing such restrictions.
