Look up the old game called "Crossbows and Catapults"...
We wasted HOURS upon DAYS upon WEEKS playing this game
lawn darts, anyone?
Well of course their stupid, but the whole point is that they are FREE to choose to be stupid, and that is the big lesson Australia has failed miserably to get through it's big fat dumb head.
this is by no means only happening in Australia. i call it 'cultural hypochondria.' here in the states at least, it's not just about safety in the sense you seem to mean. sure, children's playgrounds are now these low-to-the-ground, all-plastic jokes that look more like doll houses than anything you'd play
on. it's not just kids, either. disposable coffee lids are invariably emblazened with "WARNING: CONTENTS HOT". but it's also a cultural neurosis about being sanitary. everything gets santized 20 times per use in 13 different ways. cops wear latex gloves now. and it's no longer good enough for a kitchen to
look clean: now the jobs not done until you've committed mass germocide.
i don't think at its heart it's about safety as an end in itself. not in the U.S. at least. i think it's an outgrowth of living in what one of my sociology professors called a "litigious society." no one wants to get sued, and it's not even about winning or losing a lawsuit so much as maintaining a public image.
and since businesses and public institutions invest so much into safety as a means of avoiding unpleasent lawsuits, the companies that grew up around these needs have branched into "providing service to" (i.e., advertising to the point of creating a 'need' that wasn't there before) - to consumers, as well as institutions.
