"Tiny Minority" until you no longer need a job to maintain the lifestyle. A non zero amount of people will go from not traveling, to traveling.
This is neither a criticism nor endorsement of UBI. Its just an observation.
Isn't this making the argument in favor of a UBI? The theory behind SNAP is they have to buy food instead of stupid things, but then they just buy stupid food.
Meanwhile someone who is actually having a hard time gets put in a bind because they'd otherwise be willing to eat day old bagels and whatever's on the menu at the soup kitchen in order to save up for what they really need, which is the deposit for an apartment. But you can't use SNAP for that and then the government is paying the same money for worse results.
Not UBI but this video (https://www.youtube.com/watch?v=N_GLfxaYTYI) shows (claims) rent always rises to suck up available money. Why? Not because landlords are evil, no, because once people have more money many of them want a nicer place. There are a limited number of nicer places so the prices rise since all these new people with a little more money bid up what they're willing to pay.
The same will be true of UBI and anything you think it enables. There are limited number of planes, boats, hotels, hostels so the moment everyone can do it is the moment there's more demand than supply and prices will go up.
The larger point is that it's not about if you get UBI. It's about if everyone gets UBI
