Explain To Me Again Why Marines Had To Change So Much?

The Marines are forging ahead on novel means to sink ships instead of destroying enemy ground forces. I'll ask again, why?!

But why is this better than having the Navy or Air Force do the job? 

The Marines demonstrated the ability to launch attack drones from their self-built submerged drones, [which will] significantly increase sensing and firepower in defense of the fleet. 

Seriously, why is killing a Marine ground combat capability to create an entirely new anti-ship capability that the Navy can expand more efficiently a good idea? 

The Marine Corps feared being a second Army to avoid going on the budget chopping block as a redundant formation. It chose to be a second Navy. The Marine haven't even done enough to be a redundant second Navy.

Well, really a third navy. After the Coast Guard. Which actually makes the Marine changes worse. 

NECC could become grunts to make up for that, I suppose.
