In a perfect World yes, we do not live in a perfect World and it is not so simple as many things testifies, drugs - they are banned - see how that works.
>Banning stuff will make honest people do it less and therefore present less opportunities for non-honest actors to steal this valuable data (e.g. through security lapses).
Reducing things and banning them to cater for the lowest denominator - Look at the history of things banned and tell me that that saw a reduction in crime as it don't - again....drugs.
> There are no silver bullets, we cannot solve complex issues in one master stroke.
Totally agree - but a poor stoke can do more harm than doing nothing, not advocating nothing but back to my first point if something appears broken then you fix it.
But I'll raise another issue with an analogy - if the internet was cars - would we allow people to drive without having a test. Yes cars can kill, but not like the internet is incapable of doing them same as we have seen. The internet and offerings have evolved and there are not restrictions beyond age (an artificial hurdle) that stop you doing what you like, oh and laws which are less clear in the quagmire of the internet as it is not in one country and country laws vary.
So unless you ban it everywhere, you are akin to sweeping it under the carper in one location and allowing free reign in others.
Let us remember that more crime has been committed and fraud via the telephone than via the use of facial recognition and old types of fraud - whilst banned/illegal - still prevail.
How did that ban on spam work out again - oh right, you got people who think, well its not in my spam folder so its not spam - this African Prince with loads of money must be legit as rules to block spam and this is not spam - that much I know and tada....a little knowledge driving on the internet strikes again.
Yes - no silver bullet - single solution, but banning things often works as a bad solution due to numerous factors - including human nature as many Number #1 music record that got banned from airplay will attest.
