Or having mandatory security checks in place after frequent accidents on supersonic planes is bad...
The aviation industry must be one of the most regulated ones and it's entirely necessary to guarantee the safety of passengers and crew. You don't see anyone complaining about it except Boeing who failed QA in the past couple of years and killed some hundreds of people due to their oversight.
Perhaps if the industry had been allowed to develop, we'd have some freaky ass new and innovative tech that would've abated the problem. The world may never know!
So basically "if they were only allowed to cause harm then maybe maybe one day they might have found a way to on their own for no profit stop doing that harm"? Yeah, no thank you. Also, all of corporate history shows that without a government or public pushback "will stop doing harm" never happens.
