what happens to perfectly-working, $500-$1000 cameras, when their proprietary batteries are no longer produced?

3rd party batteries will fill the niche.
Worst case scenario, you get a battery grip with a AA battery tray.
What camera are you so worried about not being able to get a battery for?

my camera doesn't use batteries

Show us a battery from a mass produced camera made twenty five years ago that can't be bought anymore.
Pro Tip: You can't.
Now consider less batteries were made for more cameras the past decade as many cameras shared the same battery. There will likely never be a time batteries won't be available. Even if some batteries go out of production the cameras can be used with external power connectors connected to custom batteries and 3D printed power adapters can be made to create battery slot to power converters.
Try to post an example of a camera that couldn't be converted somehow.
Pro Tip: You can't.

for what its worth, my Rx100iv still has its original battery and that camera is from like 2016. still works fine, maybe doesn't last the original 280 shots rating but its pretty good. if its a newer camera it probably supports power over USB so in effect you have infinite battery as long as you can into usb. And even on the off chance that it's been long enough that batteries no longer exist and you still somehow want to use this camera, it may even be possible to 3d print some kind of dummy battery to engage the contacts and then use an extension out to a custom battery pack or something. but i couldn't see going through all that effort for essentially a disposable camera.

That's because you are too young to understand how the world works. You can't even see/understand that that what you say won't occur already is for older tech that came before your parents were born. You're litetally short sighted and literally blind to reality. People will be fooling with tech from our era for a very very long time. After all of us are dead and turned to dust the fun will just be starting for generations of future hipsters, tinkerers, historians, ect.

The batteries in almost every SLR and MILC are two LI-ION 18500 cells in series

These batteries are mass produced for fucking everything and you could feasibly wire up AAs and get 50 shots of battery life if the world ended

There's actually no reason for them not to be standardized but corporate greed because canon, nikon, and sony all use literally the same fucking battery.

If they have this a bigger sensor and pasm it'd be perfect
