Whether the user is aware and opt _in_ is the issue, right? But all of the network signals that are triggered by web applications, phone apps, OS, isn't it almost always possible to get SOME information about a user's geo location? There's a theory that Silk Road's Ross Ulbricht leaked his location via a Captcha on a website, despite actively covering his tracks. I think Bitcoin's Satoshi is/was an Australian bloke living in Japan because of his wording + timestamp on posts. I was able to send a friend a little hello message via a Facebook ad by hyper targeting them (before fb disallowed that), which also confirmed their location.
