The difference is that for my friends I have granted them explicit privileges beforehand to have access to that kind of data. It's different when a stranger is scanning me, mining me for data. And actually yes I do feel like a product or mark at conferences when people come up to me and just chat me up because of the company I work for (you've heard of it) - they almost always want quid-pro-quo type interactions or otherwise don't care about me per se, but just the quantification of me that exists on the badge. It's one of the reasons I don't enjoy industry conferences that much or when I do go, I prefer not to wear a badge. And honestly, scanning from a distance is still incredible invasive. You can be the "master of your eyes" but don't get offended if I or others think you're a creep. You may not be touching me but you're definitely noticeably staring. The rejection Google Glass actually gives me some faith in the decency of people, but you're probably right, society at large will adjust because the profit motive and law enforcement capabilities for this sort of technology are too great for them not to become entrenched by media and government interests. Personally I find it inhumane and repulsive, but I'm old fashioned like that. I prefer more organic human interactions, nuance, getting to actually know someone beyond a readout on a screen. I'm a private person in an increasingly public circus of society.
