It makes no sense to remove it from a street car if it is working properly.

On a racecar you would only remove it due to class rules. Otherwise, it is unlikely that you will be able to gain a significant amount of increased braking, and then only in the dry. In wet weather on the track, abs is almost always superior, and in dry, they are only close if the driver is an excellent racer. Otherwise, abs usually gives the advantage. I am also assuming that you have excellent tires. With less than optimal grip, you will generally benefit from abs.

It took me years to get around to trusting abs because I came from a background of extremely late threshold braking (cars, not bikes). But even I like abs in wet weather conditions. I have my RX7 setup where I can control when I use it and when I don't want it. Right now, I need to replace the computer though.
