I think that's the sentiment that think-tanks have been pushing recently. But outside a very "us-vs-them" viewpoint with China, I don't think it holds true. America's Navy does it's job pretty much perfectly for defending US interests at home and abroad. We have the tactical elements that we want to field, and we maintain them in a condition so they can provide the desired effect at any time. Building more ships isn't a panacea, and in many cases it's a great way to end up having billions of dollars in rusting assets sitting in dry-dock.

It's worth flipping the question on it's head. China's ambitions are very clearly best carried-out by a Navy that can harass Taiwan and expand their territorial claims in the waters surrounding Japan and eventually even threatening Australia. This is a smart move on their behalf, but they will be contending with unfriendly airspace and ground-based anti-shipping weapons. If you want to look at it from a purely military materiel perspective, I would argue the US has weighed their options and taken a less Naval-dependent route.
