You're talking about two different issues: 1 the number of rules/laws to be enforced, and; 2 the number of people in the agency and in the field enforcing the rules/laws. Reducing the first does not automatically mean reducing the second except for the number of paper pushers and processors. There will still be strong enforcement of the laws left in place. Cleveland's Cuyahoga River will never catch fire again. Ever.
