I agree with you, but this isn't necessarily the best example. In this case, frankly part of this issue had to be resolved by relaxing strict zoning laws that weren't allowing space to be used in a way that the market demanded (offloading empty chassis). Such a measure falls under deregulation/free-market/small-government.
The other measures proposed (forcing railroads, national guards etc) are of course of a different order, but it's not clear they'd be necessary if the build-up of empty chassis at the port (because offloading in the nearby area wasn't allowed) never materialised into a massive bottleneck, because zoning laws were deregulated.
