While internet streaming doesn't have the licensing and capital hurdles that over-the-air broadcasting has, it does have its own expenses. And unlike AM or FM, where the costs to run the transmitter are fixed and don't change based on the number of listeners, the costs of internet broadcasting are variable. Each listener consumes bandwidth; if you're a music broadcaster, each listener also adds a cost for licensing.
An internet station with 1,000 or 2,000 or 5,000 or 10,000 simultaneous listeners -- like stations in this market will see over the air -- will rack up terabytes of transfer a month. If such a station is to be self-sustaining, it either needs a sales person or department, or public-radio style development efforts. National internet-only radio sales is pretty much non-existent at this point.
The barrier to entry for running a station with a few listeners is small, but to compete with on-air broadcasters in a specific market, the costs will not be trivial. More success is likely to be seen in a "long tail" approach: finding a niche and grabbing a few listeners in each market.
