This is the wrong comparison though. Merchants offer bulk discount to incentivize customers to buy more units of whatever they’re selling. I can’t buy more than one seat on the plane of its just me traveling. I can’t utilize the ‘bulk discount’ if I’m not traveling with anyone

Group discounts are pretty common for all kinds of services, they are pretty comparable to bulk discounts for goods. You might not use two seats on your own but you might bring along a friend.
