Giving up part of your freedom and privacy is inherent to a democratic system. We elect people to make decisions for us, to serve and protect. In order for them to do their jobs properly they have to hold a a certain amount of freedom when it comes to these areas. We could also go back to a nature-state in which people get to play by their own rules but I reckon we all agree that having a law to obaide makes everyone feel a lot safer. Of course those in power should always be restrained of abusing that power, that goes without saying.
