Governments instituted to secure rights, by prosecuting criminal acts after the fact, are derelict in their duty when they seek to impose prohibitions on liberty, on the chance of preventing crime. Though one can evaluate performance for the former, one can never prove or disprove the efficacy of an abrogation of a liberty in crime prevention.
When a government stoops to sweeping regulation, it is declaring its incompetence in prosecuting crime. Worse, by regulation, it puts the burden on the innocent people that should have been born by the criminals or the servant government.
The end result is a nation of people who are no longer free, but constrained to actions permitted by the government and its bureaucracy. In other words, that which is not permitted, nor mandatory, is forbidden. That IS the death of liberty.
