The point behind learning to fight on the ground is so that if you end up on the ground, you have an advantage.
You realizing rolling on the ground, I might also have a knife or gun, right? You realizing that if I throw you on the ground and you land on broken glass, gravel, and rocks, you are going to be in much more trouble than me, right?
Every fight is different, and you have to use the skills you have fitting the situation. If your plan is "No one is every going to take me to the ground" that's not a robust plan.
