Are Doraemon's Gadgets Mass Consumer Goods or Luxury Items in the 22nd Century?

Okay, this is an interesting question, let's talk about it.

Doraemon's Gadgets: Future "Pinduoduo" Best-sellers or "Hermès"?

Regarding this question, the answer isn't black and white. Simply put, most of Doraemon's gadgets belong to mass-market consumer goods in the 22nd century, but some are high-end items comparable to "luxury brands" or "professional equipment."

We can understand this better by looking at it from a few angles.

Why are most considered "mass-market consumer goods"?

Think about what kind of robot Doraemon is.

Doraemon is a "defective" robot In the original story, Doraemon was a "defective" model from a robot factory, becoming clumsy due to a loose screw. He was later sent to robot school where he performed poorly, and was finally bought by Nobita's great-great-grandson, Sewashi's parents, during a clearance sale. Think about it: something a family buys at a clearance sale wouldn't be top-tier luxury, right? It's like the discounted goods we snag at outlets or during Double 11 sales today, indicating it's aimed at the mass market.
The purchasing channels are very "accessible" How does Doraemon get those futuristic gadgets? He often orders them through the "Future Department Store" or "Future Mail-Order Catalog." Doesn't that sound like our Taobao, JD.com, or TV shopping today? He even worries about meeting minimum order requirements, waiting for discounts, and sometimes buys trial versions or cheap items with bugs. If these gadgets were luxury items, the purchasing channels would be boutiques or custom orders, not open-shelf department stores and mail-order catalogs.
The prevalence of the gadgets In the stories, we see Doraemon's sister Dorami and his classmates/friends also possessing various gadgets. This shows that in the 22nd century, these "future gadgets" are quite common, much like smartphones or household appliances are today. Basic items like the Take-copter and Anywhere Door are probably common means of transportation, similar to shared bikes or private cars now.

So, which ones count as "luxury goods" or "professional equipment"?

Of course, not all gadgets are that "down-to-earth." Some are far too powerful to be commonplace.

Gadgets that alter causality: For example, the "What-If Phone Booth." This thing can create a parallel world and change the world's fundamental rules. This is definitely not something ordinary people could own; it's more like a strategic, state-level device requiring strict control. If everyone had one, chaos would ensue. This is absolutely the "luxury" among luxuries, possibly even non-commercial.
The Time Machine: Although Sewashi's family owns one, "time travel" in the 22nd century is strictly regulated by the "Time Patrol." Unauthorized time travel is a serious crime. So, the Time Machine is more like a private jet or yacht today – while the wealthy can own one, they must follow strict laws and regulations; it's not something you can use freely anywhere. It belongs to the category of high-end, regulated special goods.
Rented gadgets: Sometimes Doraemon mentions that a particular gadget is "rented," needs to be returned after use, and the rental fee is expensive. This indicates that some powerful or specialized gadgets are unaffordable for ordinary families, who can only rent them temporarily when needed. It's like how we wouldn't buy an excavator just to renovate a house today; we'd rent one instead.

To summarize with an analogy

We can imagine the 22nd-century gadget market like today's car market:

Take-copter, Memorization Bread, Pass Loop: These are like ordinary family cars or electric vehicles, such as Toyota or Volkswagen. Affordable, within reach for most households, standard mass-market consumer goods. The cheap items Doraemon buys might be like used cars or discounted stock with minor flaws.
Anywhere Door, Deluxe Dinner Set: These might be like premium German cars (Mercedes, BMW, Audi). Excellent performance, higher price, standard equipment for middle-class and above families, but not unattainable.
Time Machine: This is akin to a private jet or top-tier supercar, like a Gulfstream or Bugatti. Playthings for the wealthy elite, subject to strict laws and airspace regulations.
What-If Phone Booth, Dictator Switch: These aren't even commercial products; they're equivalent to nuclear launch codes. They belong to the category of national strategic equipment, strictly prohibited from market circulation.

Therefore, Doraemon's four-dimensional pocket is like a super warehouse filled with everything from "daily necessities" to "high-end rental equipment." Most of what he pulls out for Nobita are "mass-market consumer goods" within his purchasing power.
