The point is, smart glasses (which to be clear only take a picture when a button is pressed, just like any other camera people own) are not different than any other camera.

Also in the US there is no legal expectation of privacy on public streets. Plenty of public facing webcams are available for viewing.

Passing a law regulating the shape of a camera body is just stupid. Outlawing camera glasses makes less sense than outlawing camera flowers.
