So you're saying if I build some gigantic gizmo on my property and you see it, you won't try to copy it? Cause that's not what you're implying.
If you let photons bounce off your object and those photons leave your property and strike my retinas, again, all bets are off. Keep your photons to yourself if you don't want me making use of the information they carry.
If my intended use was to profit out of it, how am I gonna do that hmm?
Whether or not you can successfully make use of your idea isn't my concern, you're still free to try which is what matters.
That's part of property rights, you are starting to deny the whole thing now.
No, it's not.
