I’m sure the flames will start here, but sometimes so-called “liberty” is an impossibility as a nation grows up. For example, should I have the liberty to put anything I wish down a drain? Why not? How about something toxic? Why not? You limit your own “liberty” all the time when you agree that stopping at stop light is a “greater good” for the community than liberty to go whenever you want. Or, perhaps you believe all law is simply tyrannical oppression. If so, you will never be happy in a country. You need your own island.
I think that you are confusing or intertwining a society that establishes government for the preservation of liberty and the concept of anarchy sir.
To use your example of pouring toxic chemicals down the drain, it is not an infringement of individual liberty for a community to prohibit such activity by law and prescribe consequences for breaking that law. In doing such a thing one would be causing harm to others via his or her actions and thereby infringing on the rights and liberty of others.
The exercise of liberty does not include the right to cause harm to others.
