Consent or not, most laws allows that anyway. This is the publication that is usually limited and usually only in cases where people can be too easily recognized. These exceptions are a bit vague on purpose so that it is still easy to publish stuff without having to ask every single person you came accross in the street for their consent.

But the world has changed. For instance last year I recognized my father in a travel video published by a youtuber from another continent. You would have thought that it is no big deal if a latin american can record video of people in europe because its target audience is unlikely to recognize anyone. Yet here we are, people nowadays can have relatives, friends and or former colleagues spread all over the globe, or consuming content published online but targetting a public from very far away.

Until now it wasn't a big deal as it was still easy to spot someone recording a video from quite far and move away or hide your face. And we would rely on good old shame and citizen vigilance to spot people recording kids for example. "spy cameras" used to have such a crappy quality you couldn't do anything too bad without getting close and in good light. Now it becomes a bit complicated with these glasses.

In the US, you have consented. It is settled law that there is no expectation of privacy while you’re in public. This is how paparazzi, among others, can work their trade. If consent were required, every star would ban photos of themselves in public. They can’t and nor can you.
