The use of a bootloader allows us to avoid the use of external hardware programmers. (Burning the bootloader onto the chip, however, requires one of these external programmers.) Isn't the Arduino board itself the external hardware? So why would you need a bootloader then?

Bootloader? little confused here.

No, the Arduino is the board AND an AVR chip with a bootloader.
Without the board, the AVR wouldn't have serial comms, and without the AVR the board wouldn't do anything.
