So I’d argue it’s both a solution and a tradeoff.
1. Allow performance to degrade
2. Allow longevity to degrade
3. Allow the battery to be replaced
4. Some revolutionary battery technology that doesn't degrade??
What solutions are you thinking of?
So if you did that and instead of a battery combined it with a (relatively large) capacitor (or some sort of amazing spring) you could have the iPhone equivalent of a shake and shine flashlight. (One bonus being that there would be absolutely no holes, as it would not be possible to charge it via a wall outlet).
It would be completely impractical, but there wouldn't be a battery, so the battery wouldn't degrade. The alternative storage mechanism might degrade, and who knows what all of the shaking would do to the delicate electronics, likely nothing good.
Anyway, I think it'll catch on. I look forward to watching young people on the train shake their iPhone vigorously before making a silly face and taking a picture of themselves in 10 years time.
Wrong company, pal. Apple historically decides for the user. Heck, they still do it with their App Store. Often that may go right, but not always.
Imagine that some cars allow the gas tank to be changed by the user. But this one doesn't.
Imagine the company that makes the car never mentions the shrinkage or the gradual reduction in top speed, and has no program or system that allows you to fix this - beyond buying a newer car.
To try to salvage your analogy, I'll put forth an anecdote. Last year I restored my deceased father's 1988 Bronco II. One of the issues it had was low fuel pressure, which I narrowed down to the in-tank fuel pump (the Bronco was over-engineered and had two pumps, one in the tank and one on the frame). It wasn't able to push fuel fast enough for the engine to run at top performance. Sound familiar? So I had two choices, replace it myself or take it to a shop, kind of like how you can attempt to replace your phone's battery if you know what you're doing, or take it to a repair shop and let a pro do it for a fee. I'm a competent shadetree mechanic, so I did it myself and saved a few hundred dollars, and it is back to normal operation again.
I've bought dozens of Android replacement batteries and the only batteries worth the cost of shipping were actual real OEM ones. And those always cost >$60. Knockoffs would start out decent and then die within a few weeks to months.
Apple's approach gets my vote. You get the upside of built-in battery and the peace of mind when you do need a replacement.
[Just to balance that, let me be clear that Apple's choice with regard to crippling my phone pisses me off. I just replaced an iPhone 6 that felt painfully slow and now I know why (I had tested the battery and it was at 75% -- I didn't realize replacing it would speed up the phone).]
The easiness of replacing the battery has gone up with iPhone 7/8/X compared to iPhone 6. You can verify this on iFixit guides. The iPhone 6 is _relatively_ easy to replace because you don't need say a heatgun. You do need some special screwdrivers which you gotta buy. You can, on iFixit. I just bought a whole kit (on sale during Black Friday).

20 EUR for mine: https://shop.fairphone.com/en/spare-parts/fairphone-2-batter...
Replacing any parts on my phone is very easy. Only thing is that the main module with CPU board etc is ~300 EUR.
It really is DIY. There are thousands of guide that can be followed successfully.
Now, I completely agree with the design decisions of the iPhone. The completely sealed body is great for water resistance and having the battery replaced is still pretty cheap, especially if you use (I usually just let someone replace with a 3rd party battery for cheap, as this usually takes place after warranty expired).
The battery needs to have extra space (or bad things will happen) so it effectively has to be fixed on one side inside the body. Gluing it is a pretty cheap solution to that problem.
My iPhone 5 also did that, after a while, it worsened so much that the screen colors became affected. I took it to an apple store, paid the fee and had them replace the battery.
IMHO a swollen battery is a huge risk, and apple should have replaced my phone without charge.
Anyways, be careful and if the battery is swollen, it's time for yet another battery change :)
A great way to increase the odds of an explosion near your face or office desk!
With a good heat gun and toolkit, it's doable in anything from 15-30 min (more if the case is bent or damaged from falls).
There aren’t only two solutions to this problem.
(Technically you can still replace the iPhone battery, unfortunately it isn’t trivial like in the bad old days when phones didn’t have high def touch screens.)
