First off, false equivalence - there is no "instead of", what the police do or do not is unrelated to the reduction of parking spaces.
Second, implementing safety by modifying the physical environment is vastly superior to anything else because it scales. There's no longer a need to educate every single person who will use every intersection in the city every day on how to do it safely, nor a need to ensure x police officers are present. The physical design creates an environment that is safe by default.
