Hindsight is always golden but ths particular idea always seemed to me to be the handiwork of investors & execs in the Silicon Valley bubble extrapolating their needs and wants to the rest of the general population.
This reminds me of the urban legend of a Hedge Fund exec's kid who didn't know the word "airplane", only "private jet".
Of course the valley is for the reason, yet for some above mentioned people it may look like a business opportunity. Anyway, they raised 2M - peanuts for VC to explore on practice whether it is opportunity or not.
Smaller business jets don't have the fuel range to do a coast-to-coast flight non-stop with passengers. E170/190s can be fitted with auxiliary tanks for coast-to-coast corporate shuttle flights.
