> Why do you buy cell phones or laptops today, knowing that future ones will be better or cheaper?

Direct practical utility.

> Why buy some food today, when you know your purchasing power will be greater next month?

I don't eat, i starve, i die.

> Why pay for housing when prices are falling, knowing your contract will be cheaper in five years?

Now there you get into something interesting. Though the five years view is comically long.

You just demonstrated the concept to which I'm alluding. There is a balance of time preference versus saving preference for absolutely everything in an economy based on the subjective desires of all participants. For some people, this will be cell phones, or cars, or fancy shoes, or little purse dogs. They won't save forever, living just to get by, for some uncertain future when they can have more stuff. There is no deflationary spiral, there's a balance point where it stops.

This dangerous idea has been used to justify all forms of crazy economic intervention since Keynes formalized it. The notion of a currency having to depreciate is a direct consequence of these policies, all based on a fallacy. No matter how counterproductive these policies are, they're still applied. Look to Japan and Switzerland as recent examples. Japan has massive stimulus, the Yen is dropping, are people spending more, no, they're saving for the future, knowing that their savings will be worth less, so they need more of them to get by - no spending on unnecessary items. Switzerland is paying negative interest rates on savings accounts, so people have to save more to offset that.

There are lots of things to dislike about Bitcoin, but its value increasing over time isn't one.

What you are doing is conflating a commodity with a currency.

Anyways, why the Japanese is saving is that even 2 decades later they have a private debt overhang from the 80s boom.

Expect Europe and North America to follow much the same pattern (already a decade in shortly).
