You underestimate
A. how little some people care about their privacy and how much bullshit they'd put up with to access whatever content it is they're trying to get to (consider that most people don't even use an adblock) but more importantly,
B. the endless greed and lack of fucks companies have to give. They clearly don't give a shit about what they're doing being legal, making the consumer wait longer doesn't mean they'd actually read it nor understand, you easily just scroll your phone a few seconds before you click continue, and having to provide video is a really ridiculous breach of privacy as well as massive data mine, the companies would lap it up, all at our expense, how is it not shifting responsibility to the consumer?

The solution is simple - stop companies from being allowed to write these convoluted pseudo legal walls of text that basically free them of as much responsibility as they can get away with, to allow access to services, especially things like free fucking fries which aren't free at all, they exist to get your data, offering them more is not the answer.
