You know you're in trouble when you're relying on licensing to make it possible to make money in a business. Either you're capable of offering a service that adds value, or you're not. If the value is *only* established by artificially restricting entrance to the market, then you don't have a business.
It seems to me the biggest issues facing the drone industry are that
(1) all of the major platforms are built outside this country and are 'closed source', so we have limited capacity to develop custom applications without first re-inventing the wheel.
(2) we're still waiting on regulations that *enable* businesses. We can't fly beyond line of sight, or autonomously without an expensively trained operator.
(3) operations in built up areas are heavily restricted
The points above mean that the only business currently possible is 'pay by the hour camera operator' - which is not attractive to most business clients. Construction companies want to either just 'use a drone' or 'pay for a national service' - not have to find a local 'man with a van' who may or may not be able to provide data that their departments can use. The same applies for most other suggested use cases; they need to be either cost effective to run in-house, or available as a consistent service nationwide.
In short, we're still trying to develop the technology and discover the business models that will work - yet the confused regulation and uncertain environment severely restrict experimentation.
