The ISO-9660 file system was originally intended for CD-ROMs (note "ROM": Read Only Media). It is was designed as a writable file system. I have no idea what Unetbootin is doing, but it obviously NOT directly copying the ISO-9660 disk image to the flash drive.
There is no reason to make the ISO boot image itself writable. If you want to create a self-contained bootable Linux system on a flash drive and use it as a rwad/write Linux system, that is something else.
