alt Hacker NewsDespite being full of arrogant intellectual superiority, evidently the majority of the HN crowd has little understanding of basic economics.
While I personally wouldn't go as far as "Society profits immensely from their contribution", these types business people do serve an important function in the economy.
Much like traditional middle-men sellers, commodity speculators, insurance providers, and the like, domain name re-sellers take on the risk that no one else are willing to bear at some particular time (that the domain they're "squatting" could be worth nothing in X years). If and when the domains they're "squatting" later on become more valuable, either through their own direct efforts, or by re-selling them to other parties that can make better use of them, then the profits they make from such transactions are justified for the aforementioned risks they bore.
What risk? They contributed nothing, they have performed no function. Their only claim on it is having been first on the dictionary attack and laid claim to a bunch of useful letter combinations without providing any value or service.
If they didn't do any of this that combination of letters doesn't disappear, it just goes back to being available from the primary registrars.
The squatters are just vacuuming up some of the profit off people that would/could use that combination of letters to actually provide a service.
I don't view middle man parasitic behavior as valuable, and see no market value performed here other than extraction.
