Why don't they package/sell one with the rpi? It isn't an optional peripheral.

It is optional, though. The Raspberry Pi 5 does support USB-PD. There aren't very presently very many USB-PD chargers that support the 5A@5V mode that it prefers, but they do exist. And like what happened with the Raspberry Pi 3s and 4s (which also had somewhat peculiar power desires and also did not include a power supply), additional third parties will come forward to produce their own versions of Raspberry Pi 5 power supply. (It's only natural, and history supports this happening.) But even on a desert island: It can be powered through the GPIO header just like all other previous versions, if that's what you want to do. Just put a reasonably-stable 5V supply on there that can output 5A, and power it up. No big deal. Also like with previous Pis: A person is also free to goof around with using whatever USB bricks they have laying around. Might work, might not -- but it's a device that is intended to be a learning tool. Or: Buy a kit from a kit-maker like Vilross or something, if you need accessories included all in one box. (At any rate: Raspberry Pis have always just been bare boards, not complete systems.)

      Someone even hacked these to 8G but that required reballing a 200 pad chip.

        I've read about that. The most difficult soldering I've ever done was swapping an ATMega 2560 chip between two boards with a very basic hot air station, and that one still doesn't work right (but it works well enough to be useful). Hacks like this are very impressive.

        The QFP or the BGA version? Either way, that's already pretty impressive to me, I probably couldn't do it. The best I've done so far on that front is fixing a board that had a layout error which caused the pads of a USB connector to be offset by bridging the gap with individual strands of copper. I also hope to never have to do something like that again :)
