So do people who mistakenly blow through a stop sign or make any other potentially fatal mistake.

I regret to say that I don't see the point of this remark.

As a licensed driver you're required to know what to do when approaching an unguarded intersection where you clearly do not have right-of-way, and not interpret the lack of a stop sign as a green light.

Some countries have a more finely developed concept of right of way than the USA and Canada. They have signs which indicates right-of-way paths through intersections via map-like diagrams. Also, signs which indicate a change in right-of-way status of the current road.

Removing a sign which negates a road's right-of-way status will likely cause an accident.
