I wouldn't call it a rigid standard by any means. I think of it more like common sense. I'm not accounting for those that are typically more paranoid than most.

Nothing about security is absolute; it's all about risk management. Sure the impacts are huge here, but what are the likelihoods? When protecting yourself (digitally or physically), everyone takes a reasonable approach and draws the line on what is acceptable to them. In this specific case, if your second factor is compromised, your first factor is still intact because it's different for each resource. If you use strong keys for your first factor, then you would have to be specifically targeted for both factors to be compromised. Unless you're someone really important, the likelihood of that happening is next to zero.

Typical drone ground stations w will use circular polarized, directional antennas for live video signal, however you won't have a CP directional on the drone (for obvious reasons) and will use omni directional instead (not very directional). This means that it's pretty easy to disrupt a 1.3, 2.4 and 5.8GHz signal (or even 900MHz) with simple, cheap hobby gear when you're closer to the drone than the operator.

For control (usually 433MHz or 2.4GHz), you won't be using directional antennas on either end-point. Therefore, it's pretty simple to disrupt that signal using cheap, hobby gear as well.

You're right about the GPS when using autopilot and waypoints, that's another story. GPS receivers on most drones can only be disrupted when there's a strong RF signal (or resulting harmonic) in the drone's near vicinity. I'm not sure what kind of gear you would need to blast a point in the sky with ~1500MHz to disrupt the GPS.

Commonly used GPS units on drones rely on GPS lock to function. These are also radio frequencies which can be overwhelmed in small areas. I know this because using an overpowered 1.2GHz transmitter on the drone will negatively effect GPS satellite lock. Knock the sat lock down to below 6 and you got yourself a lost drone.

You can detect the drones by monitoring commonly used radio frequencies, like 433MHz, 900MHz, 1.3GHz, 2.4GHz and 5.8GHz. It's not hard to flood those frequencies with plenty of noise to disrupt control as well as video stream. I would guess these drones are not flying LOS, therefore disrupting video and telemetry would make it very difficult for a drone operator to effectively maneuver, make any interesting video, and even return the drone back to safety.

They probably don't want drones simply because people will start taking drone footage to leak the activities happening on the ground.

Shouldn't the right and wrong with regard to viewing people in their private yards be all about intent? For example, if someone puts a stepladder against my fence for the purposes of observing myself in my backyard, then that person has the express intention of viewing me in a "private" area. This is what the Peeping Tom law is all about.
Now, just because a drone flies over my neighborhood with a camera doesn't mean there was any intent to violate my reasonable expectation of privacy, unless the drone operator is flying over my property to purposefully observe/film me in my yard. It's also important to consider altitude; is a camera flying drone flying at 100 feet over your yard ok? 200 feet? 2000 feet? Where do you draw the line before sounding ridiculous?
I have light aircraft flying over my home and yard every day at atltitudes of less than 300 feet (and I'm not near an airport). I don't know what their intentions are, but I do know that privately operated drones must strongly account for weight. You won't find serious photo gear with telephoto lenses on a private drone, whereas you can load many pounds of camera gear on light aircraft or helicopters.
Look, if a drone flies over my yard at 100 feet or more and keeps moving, I just don't care. If it hovers for no apparent reason, then I'll investigate. Drafting legislature that is so broad as to say that any drone flying with a camera over any private yard is breaking the law is just plain stupid.

It's time to boot, do your boot ROMs know where your disk controllers are?
