A Hole in The Fence

Life seems straight if everybody follows the rules.However life can be very boring too if everybody just follows the rules. Do we actually think about why there is a need for rules and regulations. Why is there a need for fences and walls and gates and trenches?
From time immemorial, these elements seem to be part and parcel of our life. Can we live without them? Do we really need them? Are fences built to keep others out or are they keeping us in? Who are the prisoners, those inside or those on the outside? Who is protected, people inside or people outside?
I suppose we have to look at in context. Fences around our houses and fences around correctional facilities serve different purposes. A fence in the zoo and the fence around cattle in a farm stand for different reasons.
Why is there a need for gates and walls? Must we always filter what goes in and out?
I would choose to think in a perfect world, there would be no need for fences to keep people out or the reverse. There would be no reasons to fear the 'outside' and there would be no reason for those on the outside to be suspicious of the 'inside'. Where do we stand as civilized humans when we do not respect one another's privacy and belongings. Everybody has a responsibility to each other that goes without saying.
Stop, and think, where are we now? Are we safer today than we were yesterday? Look around you, are there more fences, gates and walls?
Fences, walls, gates. trenches, barricades, obstacles don't only exist physically but they also exist within oneself, within communities, ideologies, beliefs, norms and even philosophies. Thus, the question again? Are we really free? Is there or will there ever be a perfect world? Freedom is just a word.
