Sorry, but you're wrong!
There was a kernel, it was called nuKernel. The boot ROM was used to launch the machine and provide the hardware information. You could replace the Finder with any other app and make the computer boot and work, but the System file was necessary for anything to function.
For the WaitNextEvent thing, what you describe is cooperative multitasking in an OS without memory protection.
Oh.. and DOS was an OS too...
