How do you measure "is it worth" without a good idea of the risks and costs involved in the decision making? Just because it doesn't directly answer your question doesn't mean it's not applicable.

In fact, I'd argue the risk factor is significantly different across startups, so exploring the tradeoffs is the only way to approach the problem generically.
