What are the most notable examples of regulation holding back new technology? There has been a lots of talk recently about encouraging innovation through deregulation zones. The idea being that, for example, having a city with no regulation on drones will spur a great deal of research into the technology. On one level, this does make a certain amount of sense. The easier it is to do research, the more research we expect to see.
That said, other than studies with human subjects (where the rules really can have a dampening effect), I can't think of an area where regulations are clearly having a big negative impact on research. When a technology is promising and well-funded (as with drones), companies don't seem to have that much trouble working with the rules.
I assume I'm missing some obvious example. Any ideas?
