What you are assuming is that:
I'm not actually bothering to assume much if anything at all.
a) the internet filter is 100% effective
Irrelevant. Rarely is anything 100% effective or without some wriggle room for improvement. Unreasonable to expect a url filter to get it immediately right when we still can't even do that with spam filters.
Yet I'm quite happy with the level of effectiveness my email provider achieves in relation to filtering spam ... how about you ?
b) there will be no false positives
See above. I'm willing to suffer the odd/rare brief inconvenience in the form of collateral damage/friendly fire when it comes to "false positives" in comparison to predicted far greater ratio of "true positives".
"Near enough is good enough" is a well founded Oz attitude after all, and one that I am more than willing to continue to uphold.
c) it will not slow anything down
Another irrelevance, especially considering standard advancements and how quick they come. Any slow down would barely even register as a speed-bump in the overall scheme and progression of things.
d) it will only block what is _strictly_ illegal.
I am quite confident that it will be used to try and block as best it can that which is deemed "strictly illegal" now, and also what else is later deemed to be illegal as established by common concent of Oz society by way of usual process in terms of governance etc.
In short, I would expect it to remain flexible enough to not only deal with things judged illegal in the here and now, but also in the future.
Things that none of us have The Right to promote or partake in as judged by the majority for the benefit of the entire nation.
