I believe that as more drone detection and identifying technology is implemented it will become easier for the FAA to enforce the regulations. Excerpt taken from a fairly recent article follows:
Commercial drone operators flying responsibly want more enforcement to keep rogue operators in line. A recent GAO report sheds some light on what the FAA can do to enforce drone laws.

“FAA officials told us that given its overall responsibilities for aviation safety and the lower risk posed by small UAS compared to manned aircraft, its resources for actively pursuing unsafe small UAS users are limited, and identifying such users is challenging,” says the report.
What can the FAA do? The GAO report describes three options:
“FAA officials told us that the agency is following its “compliance philosophy” to help ensure users abide by the small UAS regulations,” says the GAO report. “Under this philosophy, FAA’s approach involves three types of possible actions: (1) compliance actions, (2) administrative actions, and (3) legal enforcement actions … The compliance philosophy also calls for the FAA to emphasize the use of compliance actions over enforcement actions whenever appropriate.”
“Compliance Actions” are about education, on-the-spot correction and notification. “Administrative Actions” are letters of correction or warning letters; and “Legal Enforcement Actions” may involve civil penalties and/or suspending or revoking an operator’s license.
“According to FAA’s data, from June 7, 2007 through May 2, 2018 the agency took 420 compliance actions, 49 administrative actions, and 49 enforcement actions against small UAS users; the data do not distinguish between recreational and commercial users,” says the report."
