> Imagine a world in which prices regularly go down
That world results in a lot of people individually deciding "why buy now, when I can buy for less later" and sitting on their money.
That in aggregate makes the economy much worse.
You're up against human nature here. Money may be an arbitrary numerical denomination of value, but people's behavior around it and how that affects the economy at large need to be accounted for. Having prices slowly creep upwards over time (low inflation) tends to result in more, better things sooner.

Why do people buy iPhones today knowing that they can get a significant discount in 6-12m for that same iPhone
The state of tech goods is such that they become obsolete and have a finite lifespan, due to battery and compute needs, as well as the "fashion" element of having the newest thing.
The price is dropping over time because you're getting something literally less valuable. The analogy would be, would you pay the same for a bag of rice expiring in 2 years, as one expiring in 2 months?
The argument you're trying to make, would be valid and convincing if Apple lowered the price of a new iPhone with each subsequent release.
Because an iphone is a status symbol, and in 6-12m that same iphone won't grant the same status, a newer more expensive one will.
>That in aggregate makes the economy much worse.
Does it really? A lot of our problems seem to stem from conspicuous consumption. People will still need things (food shelter clothing) and that will motivate purchasing. "Oh n0es people won't buy flavor of the month consumer garbage, what ever will we do" just doesn't track.
> Does it really?
It does, really.
Conspicuous consumption is a miniscule part of the economy, and for every person whose conspicuous consumption drops, you'll have 5 people who can no longer afford food and shelter.
If you'd like to learn more, I'd encourage you to take an economics class at any local community college. Intro level should teach you about lots of new things including this, much more than you'd learn reading HN comments.
