In most parts of the world, if a person is in a public space, anyone can take a photo of that person, including shop owners. This photo could be considered as a type of "fingerprint" for that person. The only important difference is that in some countries, you are not allowed make money off of such photos.
The Internet is a lot like a big public space, and possibly worse - while you are using certain services (web pages or apps), it might be argued that you are actually "on premises" for that service provider.
The best we can do now is more and more education about what can go wrong with such data collection.
Yes, but taking photos is expensive, fingerprinting online is cheap. Also, there's a difference between taking a photo of the eiffel tower and taking a photo of a bunch of other tourists there (legal), or intentionally targeting and photographing an individual and creating a database of those photos (illegal in most countries).
