It’s been long enough that people of forgotten what’s it’s like. Cameras still have replaceable batteries, there are several benefits:
I can have two (or more) batteries, if it runs out I just change it. I don’t need walk around with a USB battery pack and cable hanging off the device preventing me from using it properly.
I can put the battery on charge somewhere and leave it, even if not completely secure, because just the battery not the device. This way my expensive device and my data is not at risk.
I can use 40+ year old cameras, because I can just put a new battery in. This is not something you can do with newer device, e.g. and iPod and you can’t even find anyone who will fit them for the older models.
Battery tech moves on. There are now some batteries with charging ports on them. Other batteries offer more capacity than the original ones. Apple even did this once for me, when MacBook Air batteries were fairly easy to replace, I had mine replaced (it wore out) at the shop and they put a slightly bigger one in, which was the standard on the newer models.
