We do acknowledge the problems, at least those with a reasonable odds of existing. That is why most of us advocate restricted access.
As for your apparent fear of flying cameras becoming common, don't you think they had better develop a better policy than a ban, which the masses are probably going to ignore anyway, if everyone has one in their pocket. Even the NPS recognised this, which is why it was an INTERIM policy.
We just want them to do their jobs and get on with it.
Yes - they absolutely need to do that. But I disagree that you even acknowledge the problem. I've been following these threads intermittently and many of those arguing for either full or limited access wheel out the "isolated drone flying past at altitude" example for why it should not be a problem. That's not a constructive way to address the issue.
