Sure, you can have technology that an be used in detrimental ways. Doesnt be we have to accept and allow its use in detrimental ways. We can say "this technology can be used for these reasons, but not those reasons"

We do this with everything else. You can own a gun for hunting and defense, but not armed robbery and murder. You can own a car for transport, but not to drive through a crowded parade over dozens of people. You can own a computer for work and entertainment, but not to facilitate computer fraud and abuse. And you should be able to own and use AI for its many productivity gains, but not to facilitate computer fraud and abuse, defamation, blackmail, copywrite and trademark infringment, etc.

Just because a technology has benefits, doesnt mean we have to give the negative aspects of that technology a free pass.
