Does this seem right?

Hey guys n gals, figured I'd reach out to the Internets finest. I'm about to get a drain tile system installed in my basement due to water issues. It's a finished basement. Waterproofer wants 4 feet up the wall removed, including studs. I've already cut up the drywall at 4ft but should I really cut the studs out at 4ft? They appear to just be nailed into the brick. My ceiling is only 7-8ft high as is.... Should I just gut it?
