I feel like some people I know enjoy to borrow because they like to see, even based on the condition, what it’s been through like how many people enjoyed it. A bit of an aesthetic effect more but, for some of them, it definitely has an added value. For me personally it depends what it is. If it’s an educational one that I’m genuinely interested in then definitely buy, if it’s a fiction just for a good read and letting my mind explore then borrowing is a good option too.
