When the system boots from the disk, it loads the OS into memory, so things

you to provide a writeable media (normally a USB drive) for that purpose,
but then you get back into the risks associated with having writeable media
available.
As I stated in an earlier email I am out of date on this but in the "old days" this was certainly not true. In the original Knoppix (which is the grandfather of all live systems TMK) if you had the memory there was a mode where you could load the image into memory, but this was not necessary. If you did load the image into memory things ran a lot faster. But the only files that *had to* reside in memory were those that were writable. Over the years there have been at least two different methods allowing writable files that reside in memory to dynamically and transparently be used in place of the read-only files on the original image.
I have certainly run live CDs on computers that had much less RAM than the size of the CD. 


True. And there are some limitations. As far as I know, all live
read-only systems allocate half of the physical RAM to the system, and
half to working memory. So if your machine has 4GB RM, you can load at
most a 2GB system image.

But DVDs can hold ~4.7GB. So if your machine has 8GB RAM, you can load
4GB from the DVD. Years ago, I built a live ISO with Debian, VirtualBox,
a pfSense VPN gateway VM, and stripped-down Whonix gateway and
workstation VMs. The workstation VM had just a simple openbox GUI. It
took several minutes to boot, but was very responsive afterward.
