The limiting factor in congested airspace are runways and properly
spaced runways.

RNP could do some deconflicting at an airport like JFK, but the airlines
cannot afford to implement it.

Perhaps after some of them go broke, the surviors cannot afford not to
implement RNP.

For today's benefit of RNP look at the lousy conventional IAPs at KBIH,
then look at the RNAP SAAAR IAP to Runway 30. This does little, if
anything for capacity, but it sure does improve access and safety.
