How will you prevent people from using this technology to create DIY pathogens? If the answer is "I won't" or "it'll be open source, I won't be able to", consider doing something less harmful instead.
Suppose nuclear weapons did not exist and someone was concerned about the Manhattan project — would you say that chairs enable people to build regular bombs, so we shouldn't worry about nuclear bombs?
“Harmful” can also be seen the other way. From my view within the industry, it is harmful that the tech does not exist, and the idea of harmfulness is, largely, propaganda perpetuated by elites to maintain the status quo.
One day, I will do it just because I can and because you argued I shouldn't. Then your actions will be a proximate cause of the existence of the thing.
Ideally, I would not be so controllable but a deep part of me loves the transgressive nature of fighting a puritan.
