Contentions: ART vs Paparazzi

So the ART of photography...
Following the masters like Robert Capa or Henri Cartier-Bresson -
We are often encouraged to "get closer," "be fearless.." --It's for the ART-- after all.
I took this to heart on one recent walkabout and really got bold taking street photography photos (FILM, of course) of people out, living normal life - being human.
When something, in a moment, struck me.
In a split second.
Something indescribably beautiful about them.
One woman was walking along and her hair was floating so beautifully about her face...but I hesitated. One second too long and her hair floating as she turned her head was lost.
I had three people YELL at me.
One threatened to hit me.
Because I was walking by and snapped a camera photo...
I was surprised the vehemence with which these people protested. I was a "student" after all...Just taking film photos. 
Don't they know that it is completely legal to take photos of people/everyone on the public streets and parks?
My question in this is... !
Of course, I know it may be annoying to get photographed blatantly...but don't these people (and really all of the public) realize that there are constant private video cameras on them, recording them at all times? Almost every business you walk by is recording every move you make. And someone photographing a beautiful moment of humanity is the enemy? Simply because it isn't hidden from view? An honest explanation is met with anger and violence. When they GIVE their image and privacy away to every company/business establishment they walk by and walk into? Even in some countries (ours not soon behind...) - like in England - You are filmed everywhere at every moment.

Here are some photos of that walkabout...Even the beauty didn't come thru...but the moments...
Isn't that what the masters say to do?
Don't we want a record of our everyday humanity - In beautiful ways?
Is not there great significance in catching people unbeknownst to them, looking wonderful, fragile or totally and completely human? If you ASK, the human moment is lost and a "pose" begins. It's the unawareness that creates such magic.
This is ART.
Human life.
Human beings.
Yes, every capture isn't a masterful piece. But the inspiration to do so? Isn't there divinity in that?
Where do we draw this line?
