You have a reason to make money last: if you spend it all too quick, you will not be able to continue to travel until you can earn some more. Most people are on a limited time-span trip. They may be going for 2 weeks or 2 months or a year... but they know it is a break from the norm.
If you work 50 weeks a year you may as well squandor your money on your 2 weeks off, otherwise you don't feel you are working FOR anything. For many people, work is a way to fund work... They will spend all their money on a house to work from, suits to work in, a laptop to work on, a fast car to get them to work quicker...
Doesn't make sense to me, but i can see why this lifestyle might make you want to spend your money on your 'holiday' or 'sabbatical'...
My parents encouraged me to save money, be thrifty and take care, I am a person who does not like to spend money, maybe I am cheap.
People do not like cheap people, but I am sure the stores love the people who spend money and are not cheap.
The conceptual artist Jonathon Keats actually did a thing at a Berlin museum where he made the experience of spending money. He didn't sell anything physically, but rather reduced it to the mere exchanging of money. It's pretty cool, and honestly, being a spender, I would have liked to do it.
