All cars since long before you and I were born have had a base brake system, now often called a "foundation" brake system. That hasn't changed. What has changed is the anti-lock function has a hydraulic controller and a computer controller added to the foundation brakes as optional equipment. By not replacing one of those units, you will not have that optional feature. That will still leave you with the foundation brakes. You will be able to skid the tires, just like on all the other cars out there that never had anti-lock brakes.
While logic dictates you'll be driving a car with brakes that are identical to a similar car that never had ABS, you still have to consider the possibility of a lawsuit. A lawyer or insurance investigator could convince a jury that you were partly at fault for the crash caused by their client who ran the red light because you were less able to avoid it, and they could be right. You knowingly failed to maintain a safety system your car was equipped with, even though it was optional, that could have decreased your stopping distance and allowed you to steer around their client's car. Remember, you're dealing with lawyers, not common sense.
