Just 20 steps and 18 screws to replace a battery, easy!
Probably could get the battery directly without all the other disassembly steps...
The MacBook Neo has a rechargeable battery. By the time the battery goes bad from too many charge cycles people will want to upgrade to a newer one.
I mean, yes, it is easy. No adhesive and just a couple of clips on the case. You could replace the battery in 20 minutes with little anxiety that you're going to cause damage getting to it.
As it turns out, once battery life hits a certain baseline, people prefer devices where the battery is harder to replace but larger over devices where the battery is hot-swappable but smaller.
And xray, microscope and soldering station to replace ssd.
The guy in the linked video up thread tore the whole computer down in 6 minutes. I'm pretty sure most people can manage to find 12 minutes out of their life every 5 years to replace the battery if they want. But if that is too arduous, you can pay Apple to do it for you for a mere $149, with the battery included in that price. Given that a comparable battery from iFixit will cost you $80-$100, that's just ~$50 to have someone save you the hassle of having to remove 18 screws from your laptop every 5 years.
