OK but we're talking about a general social problem (parents understandably don't want their kids corupte dby adult stuff, and some adult services vendors are unscrupulous but the internet makes it easy for them to hide.

I personally think this current version of the legislation is a good compromise. Tech workarounds are fine for the few of us that understand the relevant technology (though I have never bothered to compile DNS in my life and have no plans to do so in the future), but they are simply not practical for most people. Every time I hear someone suggesting this sort of thing I find myself tempted to say 'why worry about legislation? If you don't like what it mandates you can just write your own operating system.'

Of course this would not be helpful because writing your own OS is extremely hard beyond classroom/toy examples. And likewise, tech workarounds and even parental controls are hard for most consumers - partly by design. I have an xbox console and have been trying to figure out why it keeps freezing on certain apps for months now. I suspect a telemetry problem but it's just a guess, there isn't really any way to look at logs so it's a trial and error process because most consumer hardware/application vendors want their products to be black boxes.
