No, using TheAustrian's logic no one who did not want to be a physicist would get a physics PhD. Seems reasonable to me. Sounds like the OP is looking to scratch an itch. A very expensive itch.
Pretty sure OP wants to be a physicist, seeing as those were in his own words:

If someone has a Bs in electrical engineering (or pretty much any engineering field), can he spend ~ 6 years pursuing a PhD in physics and then continue his career as an engineer ( in other words, get jobs that require only a Bs in engineering) just in case no good physics jobs are available?
So, he's basically using engineering as a backup, and its definitely a much better backup than the typical jobs that most physics PhD's end up with. It's a completely understandable concern, and if it's a "very expensive itch" for him, then it's equally an expensive itch for vast majority of PhD's who will not be employed as physicists (physics professors).

That's BS. Look at all the posts where people are depressed because of their meagre job prospects they have after pouring their blood and guts into such a difficult thing as a PhD in physics. They most surely are worried about such trivial things.
And of course opportunity cost is not the FIRST thing on anyone's mind. But someone smart enough to do a PhD in physics should also be smart enough to think through the consequences of their actions.
You contradict yourself. If physics PhD students are already well aware of the grim job prospects that face them once they finish, then they should have expected this from the start and had a solid backup plan? The fact that it appears that most do not, suggests that most are, indeed, romantic dreamers and are in for a rude awakening.
Opportunity cost is always high for any PhD. If one is thinking about the PhD in terms of a cost/benefit analysis, then no one can justify doing the PhD as it will always yield a poor ROI. IMO, it's best to think of the PhD today as not career training or for something that will help you get a better job and hence "catch up", but rather as a "stint" where you pursue your passion in academic bliss for sometime and then start considering a realistic career in something completely unrelated. Usually this will involve either further education in a completely discipline, or they can jump into a different field using the skills they picked up in the PhD (though these options are drying up with the proliferation of relevant credentials). This will minimize the disappointment and depression that many befall many PhD graduates as soon as they realize they're not very employable.

I think PhDs are for all types of people who get them for all types of reasons. I would imagine only a small portion of PhD holders are romantic dreamers who don't worry about trivial things like "catching up". In my experience physics PhD students are more sensitive than most to falling behind because their field is so competitive.
I can't discredit this since I don't have any hard data at hand, so I don't know if this is the case. However, seeing as you admit that there is no shortage of PhD grads that are depressed about their experiences with the job market, I'm not really convinced that this is the case. Anecdotally, senior physics major and graduate students around me are extremely delusional about this topic and don't want to hear any of it when I bring it up. Reality is going to hit each and every one of them like a freight train doing 100 mph once they defend their thesis.
