Well there are many other alternatives then.

It's good to have at least one company to go this way for people who want to be (relatively) safe from theft.

Does it? Apple products have an absolutely blooming 2nd, 3rd hand markets, they easily serve 4-6 years I might even say on average.

Yes, it does, and there is no way it doesn't. If you want to argue otherwise, you'll have to logically explain how not being able to replace parts of a device leads to longer lifetimes. Because we're not talking about selling your iPad that fully works, we're talking about selling one with a broken display.

Your argument fails because you can replace parts of the device.

The goal is to make stolen components useless, not prevent repair.

You can let the parts be replaced by authorized repair shops. You can't do it yourself, you have to pay a hefty markup. This makes the replacement uneconomic for many older devices, thus creating e-waste.

3rd party repair shops don’t charge a heavy markup, which you can see by actually looking up prices. They need to compete with both Apple and people just buying a new device.
