Honestly, desire is a justification on its own. If you have limited resources, then it’s really about whether you can afford to prioritize those desires or not. For those with enough money, desire is enough of a reason to justify a purchase.
Without enough money, the question is whether the desire outweighs other more practical ways that money could be spent. When I was depressed sometimes I would make irrational spending choices because it helped me feel good and even helped me pretend I was not as poor as I actually was, by spending the money irrationally I could create the illusion of having more money than I had. This was a dangerous game, though.
