It is difficult to see how to sort this mess out, even with LVT and a free market (as opposed to a crony capitalist "free" market).
Ports and, to a lesser extent, warehouses enjoy a natural monopoly in that additional facilities are extremely expensive to construct and, as far was ports are concerned, most of the good locations were already taken centuries ago. LVT could tax away the superprofits made from the monopolies, but that's hardly going to be an incentive for the landowners to invest in additional facilities and without effective competition, the free market can do little to make that worthwhile either.
Anyone got any bright ideas? I am sure this must be something creeping up Joe Biden's priority list, what with Christmas coming up and all.
