This time cost cannot be less than a factor directly proportionate to minimum wage (local minimum wage or global minimum wage depending on economic policy).
In a sense, minimum wage is the cost of (human) time itself. You’re saying “regardless of the labor involved or otherwise, the skill involved or otherwise, the care involved or otherwise, the social skills involved or otherwise, the know-how involved or otherwise, this is the lowest you can pay someone to do something on an hourly basis (with many caveats, such as allowing employers to deduct the cost of services they provide their employees from said wage, etc). You can’t raise that cost without the cost of everything else shifting upwards by some extent with it. No one that understand economics debates that. The question is just how big this shift is.
