Classic DOS barely took up kilobytes of memory. I think that qualifies as "tiny". Megabytes is downright bloated by comparison.

Considering this is written in assembly, what is all that memory used for?

Well, for one thing, it's a graphical OS.

What does that have to do with anything? Windows 3.1 had a minimum RAM requirement of 1 MB. The base model of the Apple Lisa 2, which featured a graphical OS, had 512 KB of RAM. It's possible to have graphics without requiring so much RAM.

Because I don't have a proper heap yet. And so everything takes up 2 MB pages.

Well, graphics rendering can take up many MB on its' own...
