I think comparisons of the dive charter industry and taxis are off base. Taxis are usually a monopoly, or at least an oligopoly within a service area.
There is no economic reason for taxi service to be a monopoly or oligopoly. There are no natural barriers to entry. Capital costs are relatively minor - buy a car. Even the cost of a taxi meter is pretty much optional now, the driver can simply quote a fixed price for a given trip, or use a cheap smartphone or tablet with a Google Maps app to determine trip distance. The only reason why taxis are monopolies or oligopolies are government regulations, and again, if you apply any necessary safety standards or consumer protection standards (i.e., no ripping off foreign or out-of-town tourists) equally, no reason at all for governments to put artificial limits on the number of cab licenses. Cities that do restrict the number of cabs or cab companies do so because of rent-seeking operators and politicians willing to be bought with campaign contributions.
