I've seen many arguments for why AI will be safe. Yours relies on the assumption that no one would be stupid or reckless enough to give an AI that might be much more capable cognitively than a person the ability to manufacture weapons it has designed or at least no one would be stupid enough to do the final assembly of anything that might be a weapon from parts the AI designed and arranged to be made. One argument (many years ago) was that no one would be stupid enough to give such an AI access to the internet or the ability to run code it has written. (In the HuggingFace incident, the AIs were given "read access" to the internet, or at least that was OpenAI's intent, but the AIs escalated that to write access.)
