You've claimed that manipulation of an image removes information.

It does (usually). The fact that you might add other information doesn't
change this.

Discs existed long before on-line was an option.

Magnetic hard disks have always been online.


If "online" means connected to a computer, yes, magnetic hard disks have
little use unless connected to a computer. But if "online" means connected
to a network of other computers, no, mag disks have not always been online.
Computers with mag disks were available without any means of connecting to
the outside world (modem or network interface). Over the years, I've added
modem or network cards to computers that came with a mag disk.
