It's not that simple. Anything really important rarely is simple.
That standard, along with many other standards, laws, Acts, court precedents, etc etc, were created in the past under a different reality, where entire technologies did not exist and therefor could not have been accounted for in the drafting of those standards, laws, etc. All such make assumptions about how thoroughly enforced it can/will be along with how often it is broken which result in various levels of punishment.
Most traffic laws and their fines/punishments were drafted and codified into law with the assumption that 100% enforcement or close was impossible, but new technology is allowing law enforcement to achieve a much higher enforcement percentage than was originally understood possible. License plate scanning technology is another topic that is beginning to bring this phenomenon to public attention.
Considering the typical US citizen commits on average 3 felonies a day, 100% enforcement would result in much if not most of the population imprisoned.
There needs to be new limits set on the ability of the government to adopt new technology for domestic law enforcement and information gathering/analysis/investigation without thorough public review and oversight. Perhaps a topic for an Article-V Convention of States.
