“You can’t compare the library to the market, people come to the library precisely because they don’t want to be surveilled! By having a volunteer with a tally counter by the 3D printers, you are opening an unclosable door through which pure evil surveillance will march right in. That’s illegal! What about my rights? I don’t want my personal, private data about everything I am doing in the library shared with who knows who! Sure, they SAY the volunteer isn’t evil, but how can I even trust them?”
