This is not a good argument. We can't forbid everything just because it can be used by criminals.
By the same thinking we should forbid cash, too.
We have two ways:
Give up all freedoms, forbid anything and transform the society into a mass surveillance society where everyone spies everyone, where is no anonimity and no privacy.
Or require law enforcement to do a better jobs without people giving up their freedoms.
There is a pretty big gray area in there. Literally every society on the planet has some form of "giving up their freedoms" in exchange for some amount of security. I would argue that it's impossible to have a stable society without that. The thing that's important is deciding which rights are worth protecting and which ones are ok to give up in exchange for security (or other reasons, presumably).
