If my neighbor wanted to walk around their yard naked all the time, I'd certainly have a problem with that.
The reason people don't like freedom is because they don't want to pay the necessary price to own all the stuff they want to exert their control over.
If you don't want to see your neighbor naked, buy enough land so that you can't, build privacy fencing, make a deal with your neighbor, move, or just accept that you don't always get your way.

Generally, libertarians do consider it appropriate to be able to stop credible threats to one's person or property. So, I'd put this into "exercise aggression" no-no category.

I'm not sure exactly and I've never seen anyone tackle it philosophically, but it probably goes in that aggression category too. (How convenient is that?)
Minors are not considered competent to consent to contractual arrangements, so contrary to most libertarians preferences, this would have to be considered something like theft from the minor.
