My parents when I was young ended up having to figure out how to use digital cameras, scanners, printers, fax machines and then print, sign and sometimes even post off a letter for me to access one website which I wanted, which could take hours of their time in a process that took literally weeks. This was in the early 2000s, when scanners and digital cameras weren't exactly user friendly. They had to do this sometimes multiple times a month. Every website was different, there was no universal permission slip. But they did it. Eventually, they too got bored and gave up, or maybe I just grew out of it.
Point being, the tools have always existed, and always felt inappropriate or convoluted, but my parents at least were happy to do it for their kids 20+ years ago. From what you're telling me, they're now a lot faster and easier to access and use.
Even if the tools were made to take only a few minutes to setup, there would still be a vocal set of parents unintentionally arguing that everyone should suffer with overbearing ID tools so they can spend less time supervising their kids internet usage.
