That is unless the government can actually step up and set this up correctly: with a license auction. You bid on the right to operate the heliport every two years. License auctions work extremely well as demonstrated by radio frequency spectrum auctions and hot dog vendor location auctions.

You are definitely not a USA resident! Thanks to those auctions we have an oligopoly of carriers who charge per GB like it is a gallon on Nobel Prize winners' sperm, while delivering service that compares unfavourably with a 56K modem on a bad line.(Though there is oddly little critique about the tight control of airwaves, and having only microscopic slices for free individual use like wifi and p2p links)
That said, rotor-craft are not even required to land at a heliport; they can land anywhere that is safe unless doing so is trespassing or forbidden by a law.
A license auction would only restrict access and stifle competition.
