I guess I worded it incorrectly.

In a big company the machine to create value is already present and the company will create value whether you input value or not. If you quit your job, your company will carry on fine.

So essentially your value is small and by definition limited and replaceable (unless your in a small company).

In a startup the magnitude and expanse of value that you create is just so much bigger. You need to create value in different unrelated spaces - creating sales, writing code, hiring etc.

Its like comparing a rocket to a firework or better an engine to one of the cogs in its engine.
