I think few sailors have slept in a marina when the wind is piping. They don't go to the marinas on those days. In many larger marinas, when the wind hits 30 knots it is hard to hold a conversation, let alone sleep. The halyard are at least as loud as a boom box, and thus the owner has created a public nuisance that extends beyond his property.
There seems to be some notion that the do-gooder could cause some harm. That seems far fetched in this example (and there is no point in expanding the scope at this point) and no example has been presented. Frankly, I think some folks have unrealistic expectations of privacy in a crowded world, like the person that expects an apology when you bump shoulders on the subway.
I will stick with the golden rule; I hope others will tie anything up that I inadvertent leave loose. I try, but mistakes are always possible. For example, I have wound up several jibs; I just could not leave them flog. One opened right in front of me in only 10 knots; they forgot to cleat the line. How could I have let that go? I hope another sailor would do the same for me. Others have the right to feel differently.
If you really don't want anyone touching your boat, hang a sign that says "Don't touch her, even if she is sinking." I'm sure folks will comply, and they will post the pictures here.
