You can buy a laptop with an accessible battery even dual hot-swappable.
The main reason for having a swappable battery was in the past when you have 2 hours' worth of it when you were lucky. Now when you can easily have 10 or more is it not an issue. Yet still can get it if you want. It adds mechanical problems and contacts can wear down fast.
Also, most laptops are now thinner than 18650. Yet even internal one is easy to replace and are widely available.
Same with the phones. Do you remember old worn squeaky ones? Modern glued ones just feel more rugged (even when the display is somewhat brittle). But how often do you change the battery? Like one in 3-4 years? A big chunk of people does not use phones that long. Yet battery can be changed reasonably.
And phone SD card? Do we really need one? Do you want to hoard hundreds of gigabytes of valuable data in the device that can be easily destroyed, lost, stolen ... And they have plenty of internal storage anyway. And I can agree with the argument SD cards can significantly degrade phone performance compared to internal storage. As even fast ones are rather slow for random access. And people will use slow ones and complain.
And never had many issues with a "planned obsolescence".
The worst case I had was a Microsoft/Nokia phone, where they kill windows mobile and is barely usable even as a dumb phone now.
But otherways 4+ year iPhone 7 just need a new battery.
Lenovo laptops work fine even old T430. It is ancient yet daily use and just need a third keyboard
Home appliances work. Last exchanged was Fridge and Dryer, both about 20 years.
20 Year old car also works. Even when not looking nice. I use it like once a week so no need to fancy one.
