Why do you think people would be willing to pay more money for a product that is not mass-produced?

Personally, no.

Explanation:

I don't think most people are really in a position to pay higher for a lesser produced product. Now for some products such as produce, people have already shown they are willing to pay the higher price for organic produce so for some products no, others yes it really depends on how it benefit's the consumer.
