What's the real reason that laptop batteries are made not-accessible?

 it’s exceedingly difficult, to the extent of being practically impossible, to make a user-replaceable battery compartment that maintains waterproofing properly.

Samsung Galaxy S5 has an IP rating of 67, meaning it can withstand a depth of 1 meter for 30 minutes.

The S5 also came with a proper headphone port, SD card slot, and replaceable battery.

I guess the ancient Eastern wisdom at Samsung must be something we simply don't understand in the West!  :D

Another issue is the "coincidence" where all the oligopoly manufacturers drop headphone ports, SD cards, and replaceable batteries at the same time, so consumers have nowhere to go...

Sooner or later, this is all going to be seen for what it is:  a cartel, where all the participants benefit from the planned obsolescence as one happy family, as long as nobody steps out of line and makes longer lasting products...

While that is impressive, the unanswered question is how reliable the waterproofing is. I see two scenarios, and since I haven’t invested the time to see which path Samsung used in that model, I don’t know which it is:
1. The battery connectors are sealed, and the battery compartment is outside the waterproof area, so when wet, some current can flow between battery contacts. Perhaps mitigated with additional gasketing around the battery connectors.
2. The battery compartment is “dry”, so electrically optimal, but requires the entire battery compartment to be gasketed. Great when new, but even tiny amounts of dust on the gasket will severely compromise the water ingress resistance. Opening the battery compartment even once could be enough to make it leaky.

The fact that Samsung didn’t continue with this approach makes me suspect that it was #2, and that there were enough water ingress cases to make it unviable. I’d be interested to know what the actual result was.

It is method 2, as you suspected.  I still use an S5 and I wouldn't trust it under water...  but I do trust it in the rain, or on wet bar countertops, etc.!

I would gladly give up an IP rating in exchange for a replaceable battery.  I think I'm on my 5th or 6th battery in my S5...  if it was glued in, the phone might well be damaged by now from being "unglued" so many times?  -  also, I am enjoying the 0.5TB storage on the SD card, and I also enjoy hooking the audio output into the "Aux In" on my car stereo.   Sadly, there is nothing to attract me into buying a new phone, there are so many suckers lined up to buy the content-reduced new ones that the market for people like me is too small to care about!

So, when the S5 finally becomes untenable, I will simply buy the cheapest Chinese phone (I like Xiaomi, but Honor will work too) since these cheap phones may be sealed and unrepairable, with no ports and no SD slots, but at least they are cheap to make up for it!

I wonder why the batteries are failing so quickly? I replaced the battery once in my iPhone 4 before the phone got so slow due to software bloat that it was no longer viable to use. My current iPhone SE is still on the original battery although it's starting to get to the point where I'll be considering putting a new one in there sometime in the next year or so. That's one failed battery and one retired due to phone replacement in a ~10 year period.
