I will allow that there may be some harms which can result from unlimited copying of anything you want— but they bear no resemblance to the collision of automobiles in the midst of a busy intersection.
But physical space is inherently rivalrous, and a policy of "everyone runs a red light if they think they can get away with it" is going to have people being disastrously wrong sometimes.
I've actually ridden a scooter in places in SE Asia which basically work this way and it's... different. Less insane than it sounds, or looks like, but the rates of traffic fatality are objectively much higher.
This is why I thought it was interesting enough to comment upon.
In the same way that if everyone runs green lights, they'll collide with one another? How do you go through intersections?
"Running a red light" does not just mean "go when it's red" but it explicitly means "transgressing a stop signal". That there can be stop signals on multiple entrances also is complicating and sets up the crash.
