All of the sudden I want to buy a drone, visit Grand Cayman again and learn to kitesurf.

Drones are not permitted in any of the national parks and many other places. A few years ago an environmental group flew one past a ranch and caught the rancher dumping agricultural waste into a river. Did the rancher get in trouble -- no, he went to his paid for politician and within a few weeks there was an ordinance that made flying drones around such places illegal.
Most of the "obsession" with drones is the belief that every drone is being piloted by a peeping tom looking to video your 13 year old daughter. The media reports just about every incident involving a drone and it doesn't matter that no one was killed or hurt or that there was no property damage -- meanwhile, in nearly every town in the country a young man races his car down the street and crashes into someone else.
The sense of proportion is totally absent and all drone pilots are either peeping toms or ISIS members. So, yeah, there's an obsession, but not what the OP imagined.
As to the usefulness ... the low to mid priced ones get you into HD and 4K video with gyro stabilized 2 and 3 axis mounts. The mid and higher ones have very good 4K cameras including M43 cameras with full 3-axis stabilized mounts. There are things no other platform can do and that includes helicopters as they are too big to go many places a drone can go.
It's looking like the FAA and many MANY state and local agencies are looking hard to ban them entirely. The FAA not so much, but there are state and local agencies all around the country enacting all manor of limitations and laws. We could wind up with something that has more miles of paperwork than anything man has yet invented or conceived. There are rules being considered, for example, that would require anyone flying a drone to ensure that no one can approach closer than 500 feet and if they do you must land immediately. Fencing off an area that large or having to employ dozens of people to patrol that area are not reasonable. Rules like that could make flying a drone much more expensive than flying an actual helicopter.
