I don't really recognise any of what you're describing here - it's trivial to download almost any copyrighted work in seconds, for free, and basically nobody suffers any consequences for doing so.
Even so, it was just an analogy. There's very little stopping people just following you round recording you on their smartphone as it is. When it's semi-autonomous flying robots the size of a grain of rice, I don't believe you are going to have much legal recourse.
You're not talking about downloading copyright works, you were talking about "the death of copyright". Copyright isn't dead, it's alive and well, regardless of how easy it is to download stuff.
Not only that, while it may be easy to download stuff, it's also easy to be sued for it, and this has happened countless times. There's been a whole industry of suing downloaders and getting them to settle for $3k. So your assertion that "nobody suffers any consequences for doing so" is quite false. Ask Jammie Thomas.
Yes, you can largely avoid this by using a VPN, but not that many people do.
