>You don't have to take advantage of every opportunity.
That's irrelevant. The point is, strategies like, "always have cash on hand to take advantage of opportunities" don't really make sense, because the more you do of one means the less you can do of the other.
This is economics in a nutshell; determining the tradeoffs between two scarce resources, in this case cash and "opportunities". The solution isn't "more of both" unless the resources are infinite.
