I think you're missing the intent part of crime. Someone selling a duffle bag or producing one for production is likely not selling it for the purpose of facilitating crime, they just are selling a bag. The question with guns/knives/Tornado Cash is "what is the motivation behind the producers/service provider once put under scrutiny?" A textile mill producer who gets an order for 5000 duffle bags likely has no vision in mind for the use of the bag beyond "sell to N stores at X price for profit". The storeowner who buys the duffle bag likely also has no criminal motive and instead just wants to sell inventory at profit. Tornado Cash devs will be scrutinized to understand their main goals, and their communications/advertising strategies, likely as well as any correspondences will be considered for this determination.
