However everything the company does is seen in terms of investment... you invest in machinery and employees so that you can get more back than what you put in.
When you loan from VCs, you can't tell them "you only get back what I loaned". They want a cut of the result.
If you borrow something from the company for your own use, you are in a very real way making use of their investment.

(In fact, what we are discussing here are employee contracts where it is stipulated that such loans are of the VC variety... If you want to borrow under other terms, make a contract for it...)
