I think it's less taking a loan to buy golf clubs and more "feeling less financially stretched makes people more willing to spend money."
Example: Joe just had a kid and was going to buy a house in a good school district no matter the cost. With a higher mortgage rates, he'd have wound up house poor for a few years. With today's rates, he has a comfortable savings rate. Since he's not scrimping, he decides this month he'll buy that putter he'd been eying.
