Do you really want to make passive wardriving illegal? Literally anybody who sets up a wifi system has probably seen the list of other people's networks within a some-meter radius. How could you possibly think there's a reasonable expectation of privacy with your SSIDs?
I did not say I want to make it illegal, just pointing out that it’s not some completely bizarre idea.
I think it would be reasonable to have various restrictions on all kinds of large scale datasets, especially when they include data that is easy to connect to individuals, and especially when it was not compiled with their explicit (informed, opt-in) consent. This includes public information such as what I’m wearing, where I am at what times, when and where my wifi is on.
