In fact, I would argue that the edge cases feel even more special when you rent. For instance, my family rented a large passenger van for a road trip. The van itself became a sort of icon of that trip, and the source of distinct memories.
"Hey, you have a car, let's go do XYZ" doesn't happen to people who don't have a car. Replace 'car' with whatever else as appropriate. These social factors drive human decision making to a large degree. People might care about what others think, they might care about spontaneity, they might be influenced by their own desires and the desires of people around them.
Or consider the dinner party example. Sure, I've had dinner parties in rented spaces. It can be done, but they're not the same as being in someone's private space.
Yeah. Let's put the kids to bed while we continue our meal. Oops, forgot to rent a crèche. Want to stay over and continue chatting? Oops, forgot to rent a hotel and the space closes at 11:00.
Yes, but in life, many of the most meaningful things are the edge cases. That's what makes them special. If people don't statistically have many dinner parties, then the dinner parties they do have might be even more special. This is life, not a statistical model.
