I think the issue needs to be looked at with a different set of eyes. The question that needs to be answered is, why was the rule/law put in place to begin with?
Was it just one person looking to capitalize on a situation or was it the people who oversee an area got tired of stupidity.
If we take a good look at "why" certain laws were made, we find most of the time the problem is people. What ends up happening when a law is made, people get defensive when their told they cant do something. They only see themselves and not the bigger picture.
I would love to have a drone to use for pictures and video. I will probably never be able to use one be cause of the ones who didn't care what they did. As for the permitting of large scale move production, they were allowed to go unchecked for years. The California and Nevada sierra range is where most westerns were shot as well as sci fi. Some of the areas are on tourist maps. One comes to mind right off the bat. The area where they filmed Planet of the Apes. That would be the Trona Pinnacles. You can see the metal plates where the movie set was anchored and the scars from where they had to "trim areas".
Concerning Drone flying. Did you know that some birds will attack a drone? We were camping in a canyon that's also a common shooting area near me. The people in the camp across were taunting the birds and trying to hit them with the Drone. Another one is, we pulled into a forest campground to refill our water. We came into an altercation between two family's. The "Drone" pilot was "Harmlessly" filming people camping by flying into their camp. It seems this went on for a while. The one family was tired of it and asked them to stop. The reply was "What are you going to do about it?"
The Ranger had arrived just as it escalated. We saw him later and asked about it. His comment was how he's tired of having to deal with these things.
Vehicle modification laws were started in the 50's. Police got tired of scraping people off the pavement
Anyone who lived through the ATC/Jetski fad of the 80's could probably figure out why those got restricted in areas. This includes the helmet laws that came about in the early 90's.
My local sand dunes got so bad when sand toys became a fad that restrictions had to be made. You should have seen the outcry there.
The list goes on.
Again, when we see things being restricted we need to step back and try to see it from another perspective. It's entirely possible the permits/restrictions were for a reason.
To make video or take photos for personal use at any public place is perfectly legal UNLESS you have to use any special equipment or do anything out of the ordinary to do it. For example, you can film anything you want as you walk down a city street, however, if you have to climb a tree to see the people in the pool on the other side of the fence, well that becomes illegal, or warrants a permit of some sort. Property lines and the expectation of privacy or peace and quiet do come into play, as does continuing to film a person who has asked not to be.
I can only imagine a Ranger who has had to search for missing people, just had to deal with a forest fire, or wrote up a report of some idiot who just sizzled to death in a hot pool, now having to quell an argument between a drone pilot and a father with teenage girls at a campground.
There is a club of radio control model airplanes not far from me. It's my understanding that they had to get a license to do what they do, and that by crossing property lines or "crossing" the FAA in any way, gets thier licenses pulled.
Personally, I am currently of the opinion that one should need a license to purchase or operate a drone with a certain amount of range. To wit, that jackass in California who is flying the mannequin drone in the flight path near the airport. So the answer to the question "what are you gonna do about it?!" would be very simple. Ticket. Legal summons, marks against your professional or even drivers license. Possibly escalating to criminal charges depending.
I realize there are few property lines in a national park, and that it is public land, but so is the post office, and technically one is not allowed to carry a firearm in a post office - even if you have every applicable state or federal license to have or carry. I recognize that there can be restrictions even in public places and I dont really have a problem with drone restriction, or commercial filming restrictions.
Your vehicle modifications and ATV analogy, while being a matter of safety vs personal rights, is pretty spot on. In this case, instead of a matter of safety, it would be a matter of protection of the parks, personal rights of the people who dont want to be filmed, and or the "quiet enjoyment" of the park by others.
