An interesting side note:
If it Camp Pendleton didn’t gobble up 125547 acres (more than 200 square miles) of land between metro LA and metro San Diego (including 17 miles of coastline), it would all be counted as one and rival NY for ranking.

Not true. Why else would Boston and Providance not be one metro area? it's because it doesn't meet the 25% commuter threshhold yet.
So in order for San Diego to be a concider a part of LA's CSA 25% of the 1,400,000 or 560,000 must travel into the LA CSA for work. And that folks is simply not happening.

I'm simply saying that if camp pendleton wasn't there, that area would fill in with cities and suburban areas which would connect SD with OC which is part of LA metro.

To give reference to what is considered a "metro area", it's any contiguous area of urban development with 1,000+ residents per/sq/mi and associated suburban areas with 500+ persons per/sq/mi (which is where a rule similar to the one that unusualfire mentioned comes into play). Of course there are many definitions for metro areas, and CMA's, CMSA's etc. etc., so this is just one variation. Using the definition I just provided, one could consider the megalopolis from Virginia through Boston Metro one giant Metropolitan area with about 45 million residents. Perhaps I don't think my definition is often used, but it's what got Suffolk, VA dropped from Hampton Roads for a while so that's why I know about it

Don't forget that CMA and CMSAs are not in use any more.
