Sorry, but no. It happens All. The. Time. Bootcamp grads are working everywhere, especially in SF. Throw a stone at the next Off the Grid, and you'll hit one, the stone will ricochet, and you'll hit another. These sorts of folks are readily employed in the writing of CSS and creation of web forms, which is ~99.8% of all day-to-day webapp work.

(Also: holding a physics degree and attending a bootcamp doesn't mean you're a competent programmer. Imagine suggesting that a BS in Physics makes you a competent structural engineer. The fact that you would imply this almost makes my point for me.)
