I don't believe that we should let perfection be the enemy of good when it comes to addressing this situation. I agree that social media is problematic and something does need to be done as it's getting (gotten?) well out of hand. That being said, I also don't see this as the Govt having cart blanche authority to enact frivolous legislation.
If it isn't foolproof, does that mean we shouldn't implement
any restrictions/safeguards? If we were to believe that, then we may as well scrap the existing alcohol and tobacco age restrictions as it's impossible to - with absolute certainty - prevent anyone under 18 from gaining access to such things. Similarly, we may as well scrap driver's licenses as well because it's impossible to prevent unlicensed drivers from getting behind the wheel. Are these things illegal? Sure. But can you guarantee that these restrictions will never be circumvented? Of course not.
Now I don't mean to trivialise the topic at hand, because it is an important discussion. Is the Govt's current proposal the best option? Probably not. I note that the legislation is subject to review post implementation which - if it does get implemented in its current guise - is an important safeguard and at least provides some opportunity for amendment.
Sooner or later, I suspect we'll need to implement some form of federal system that allows for ready identification of citizens/residents/visa holders such that one can either authenticate on demand - or download some form of authenticated certificate/stamp/passkey - that allows for age/identify verification with other sites that does not necessarily require personal details to be shared with the site itself.
At the same time, I agree with many other posters that there is no replacement for parents actually "parenting" (
). Parents 100% need to take control of the discussion and education of their children, but I also think that they need appropriate support and the various social media companies + Govt cannot be absolved of any and all responsibility to police, regulate and otherwise manage these platforms and their accessibility.
