Yes, you have the point exactly, and someone else stated above, and herein lies the problem.
People don;t know what they're using, what they've bought or what its for and how important it is. A £3000 laptop is just as useless as a £300 desktop to people who don;'t know what a 802.11 draft n wireless USB dongle is, or people who go to PC World or Curry's to buy their computers.
Someone hit the nail on the head earlier, in that it should be the responsibility of the hardware company to enable security by default, and have clearer instructions on how to get the thing working. Too many wireless network setups involve pressing a button to match the MAC address, and other fiddly settings, which if failed three or four times the user just gives up and leaves it unsecured. This isn't intent, this is naiivety, and misunderstanding, cos on the BOX it says secured, so it must be right?
once we get to the point where WiFi is everywhere, and being on a local LAN means nothign more than being connected to the internet as a whole, then these laws won't even exist anymore, but until then, we're stuck.
Remember your average person needs a calculator to know what 6x9 is. With those people buying computers and wireless gear, is it any surprise that everyone leaves their security settings untouched and expect it to be fine?
