If you are buying enterprise-grade parts that are certified and have long-term support then I can agree with the price of 8k you mentioned above.
If you are buying consumer-grade electronics, there is simply no guarantee on how long it will last, and the saddest thing is that everything is made disposable these days, so you most likely won’t be able to repair it, this is especially true if we talk about laptops.
I simply don’t see why you would pay 3x-4x the price for the hardware to last 10 years instead of upgrading every 4-5 years.
