But should I have to have security and warnings?
No, but it does signify to others that the property is not abandoned.
I wouldn't have a seasonal hunting cabin or anything without putting up some security and a few warnings.
I bought the property. It is mine.
Only based on the law, which is an argument I pointed out earlier.
The question is if it is your land by the law alone, or whether it is actually backed up by principle.
The big point is that I should not have to use the property. I should not have to worry about squatters. I have a pickup truck at that house. It is rarely used but I keep the plates and insurance up to date, should someone be able to claim squatter rights to it because I don't use it often enough?
Morality is not black and white.
There is respectful squatting (most squatters are respectful and peaceful) and there is douchebag squatting. Use your general principles to distinguish between the two.
