This is nothing like Mahan.
Think interdiction. How much is interdiction, cost-ratio wise? Next to nothing.
In the times under Mahan's analysis, it took the financial might of a state (or a rich merchant company) to launch a sea vessel, and the only thing that could reliably take a vessel out of operation was either an expensive (and fixed) fortress or a similar vessel (in terms of firepower, navigation tech, officer training etc). Furthermore, sea vessels were faster and could transport more volume of goods by orders of magnitude than any other manmade artifact. I recall reading that up until trains arrived on the scene, it was cheaper to haul coal to the American East Coast from England's mines than it was from inland Appalachia.
Compare space vehicles. Fuel makes up the majority of the cargo each time, to the point where it is impractical to create a vehicle capable of orbital launch, insertion and subsequent orbital re-exit (It'd be upwards of 99% fuel). Carrying capacity is limited, with speed the only advantage, at the risk of being confused with an ICBM launch. In terms of interdiction, all it takes to disable a billion-dollar spacecraft is a bucketful of nails launched on an intercept orbit, or even a ground-based laser. There is no cover in space, plus things move on predictable orbits. If I were a marginal space power fighting an established space-based power, the first thing I'd do was to launch 10-30 rockets in retrograde orbit into the geostationary Clark belt with nails as cargo, and detonate them up there. Within 90 minutes, all satellites are out, and given the contaminated environment, reinforcement is at best precarious. At orbital speeds, each nail hits with the impact power superior to that of a naval cannon, while space craft have to have thin walls to minimize launch weight. Not exactly a winning proposition.
