I don't think that you are truly "in charge of your own destiny" at many programs. I get the comparison, but it's more like you're a startup in an oversaturated market with funders who have very little invested in you (and may not even know/care about you) and constantly demand that you perform circus acts to keep them funding you (sometimes in very paltry amounts) for just a bit longer. They will also be very disappointed if you turn out to be anything other than a unicorn.
And on top of all this, you could just be out of luck due to factors outside your control. I've seen multiple cases of well-published researchers with excellent teaching records, good social skills, and prestigious postdocs spend 2-3 years on the market and get nothing. It's a random roll of the dice, and I would discourage most people from trying it.
